Quiz Preview

  • 2. 

    Taksiran rendah adalah hasil operasi hitung dengan pembulatan ke ....

    • Bawah

    • Atas

    • Puluhan

    • Ratusan

    Correct Answer
    A. Bawah
    Explanation
    The correct answer is "Bawah" because the phrase "pembulatan ke bawah" in Indonesian means rounding down. This suggests that the operation of rounding in the given calculation results in a lower estimate.

    Rate this question:

  • 3. 

    Pembulatan ke puluhan di bawah ini yang tidak tepat yaitu ....

    • 45 dibulatkan menjadi 50

    • 34 dibulatkan menjadi 40

    • 56 dibulatkan menjadi 60

    • 79 dibulatkan menjadi 80

    Correct Answer
    A. 34 dibulatkan menjadi 40
    Explanation
    The given options represent rounding numbers to the nearest tens. In this case, the number 34 should be rounded down to 30, not up to 40.

    Rate this question:

  • 4. 

    Dalam membulatkan bilangan ke puluhan terdekat, jika angka satuannya kurang dari 5 maka dibulatkan ....

    • Ke bawah menjadi bilangan 1

    • Ke bawah menjadi bilangan 0

    • Ke atas menjadi bilangan 10

    • Ke atas menjadi bilangan 9

    Correct Answer
    A. Ke bawah menjadi bilangan 0
    Explanation
    When rounding a number to the nearest ten, if the digit in the ones place is less than 5, it is rounded down to zero.

    Rate this question:

  • 5. 

    Pembulatan ke ratusan di bawah ini yang benar adalah ....

    • 667 dibulatkan menjadi 650

    • 344 dibulatkan menjadi 400

    • 451 dibulatkan menjadi 400

    • 756 dibulatkan menjadi 800

    Correct Answer
    A. 756 dibulatkan menjadi 800
    Explanation
    The correct answer is 756 dibulatkan menjadi 800. This is because when rounding to the nearest hundred, if the tens digit is 5 or greater, the hundreds digit is increased by 1. In this case, 756 has a tens digit of 5, so the hundreds digit (7) is increased by 1 to become 8.

    Rate this question:

  • 6. 

    Bilangan 6.394 jika dibulatkan ke ribuan maka menjadi ....

    • 6.000

    • 7.000

    • 6.500

    • 6.400

    Correct Answer
    A. 6.000
    Explanation
    The given number, 6.394, needs to be rounded to the nearest thousand. When rounding to the nearest thousand, we look at the digit in the thousands place, which is 6. The digit to the right of it, 3, is less than 5, so we do not round up. Therefore, the number 6.394 rounded to the nearest thousand is 6.000.

    Rate this question:

  • 7. 

    Taksiran rendah ke ratuasn dari 3.490 - 2.160 adalah ....

    • 1.300

    • 1.400

    • 1.200

    • 1.400

    Correct Answer
    A. 1.300
    Explanation
    The correct answer is 1.300. This can be determined by subtracting 2.160 from 3.490, which equals 1.330. However, since the question asks for a "taksiran rendah" or low estimate, we can round down to the nearest hundred, giving us 1.300.

    Rate this question:

  • 8. 

    Hasil pembulatan ke ratusan dari operasi hitung 42.186 + 18.725 adalah ....

    • 60.700

    • 60.900

    • 60.300

    • 60.000

    Correct Answer
    A. 60.900
    Explanation
    The correct answer is 60.900 because when we round the sum of 42.186 and 18.725 to the nearest hundredth, it becomes 60.900.

    Rate this question:

  • 9. 

    Hasil pembulatan ke puluhan dari operasi hitung 123 x 15 x 34 adalah ....

    • 72.000

    • 36.000

    • 84.000

    • 52.000

    Correct Answer
    A. 72.000
    Explanation
    The correct answer is 72.000 because the question asks for the result of rounding to the nearest tens of the calculation 123 x 15 x 34. When we calculate 123 x 15 x 34, we get 62,910. Rounding this number to the nearest tens gives us 72,000.

    Rate this question:

  • 10. 

    Bilangan 435 jika dibulatkan ke ratusan maka menjadi ....

    • 430

    • 440

    • 400

    • 500

    Correct Answer
    A. 400
    Explanation
    When rounding the number 435 to the nearest hundred, we look at the digit in the tens place, which is 3. Since 3 is less than 5, we round down. Therefore, the number 435 rounded to the nearest hundred is 400.

    Rate this question:

  • 11. 

    Bilangan 3.735 jika dibulatkan ke ribuan maka menjadi ....

    • 3.740

    • 3.700

    • 3.800

    • 4.000

    Correct Answer
    A. 4.000
    Explanation
    The given number, 3.735, needs to be rounded to the nearest thousand. To round to the nearest thousand, we look at the digit in the thousands place, which is 3. Since the digit after the thousands place is 7, which is greater than or equal to 5, we round up the thousands place to the next higher number, which is 4. Therefore, rounding 3.735 to the nearest thousand gives us 4.000.

    Rate this question:

  • 12. 

    Taksiran tinggi dari 83 : 29 adalah ....

    • 4

    • 2

    • 3

    • 5

    Correct Answer
    A. 3
    Explanation
    The correct answer is 3 because when we divide 83 by 29, the quotient is 2 with a remainder of 25. The remainder is then added to the divisor (29) to get the next digit of the quotient, which is 3. Therefore, the estimated quotient of 83 divided by 29 is 32.

    Rate this question:

  • 13. 

    Jumlah panen jagung Pak Ahmad adalah 12.864 kg. Ia menjualnya ke pasar sebanyak 10.925 kg. Jika ditaksir ke puluhan terdekat, maka sisa panen jagung Pak Ahmad yang belum terjual adalah ....

    • 1.920

    • 1.930

    • 1.820

    • 2.930

    Correct Answer
    A. 1.930
    Explanation
    Pak Ahmad harvested a total of 12,864 kg of corn and sold 10,925 kg in the market. To estimate the nearest tens, we need to round the remaining corn that has not been sold. The remaining corn can be calculated by subtracting the sold corn from the total harvested corn: 12,864 kg - 10,925 kg = 1,939 kg. When rounded to the nearest tens, the answer becomes 1,930 kg, which matches option 1.930.

    Rate this question:

  • 14. 

    Jumlah siswa SD Brilian Smart adalah 185 siswa. Jumlah siswa perempuan  adalah 106 siswa. Maka jumlah siswa laki-laki jika dibulatkan menjadi ....

    • 70

    • 79

    • 80

    • 75

    Correct Answer
    A. 80
    Explanation
    The total number of students in SD Brilian Smart is 185, and the number of female students is 106. To find the number of male students, we subtract the number of female students from the total number of students: 185 - 106 = 79. However, the question asks for the number of male students rounded to the nearest whole number. Since 79 is closer to 80 than to 70, the correct answer is 80.

    Rate this question:

  • 15. 

    623 – 76 + 125 = .... Jika operasi hitung campuran di atas dikerjakan dengan cara taksiran ke puluan terdekat hasilnya adalah ....

    • 650

    • 640

    • 660

    • 670

    Correct Answer
    A. 670
    Explanation
    The given expression is 623 - 76 + 125. To estimate the result, we can round each number to the nearest ten. 623 rounds to 620, 76 rounds to 80, and 125 rounds to 130. Adding these rounded numbers, we get 620 - 80 + 130 = 670. Therefore, the estimated result is 670.

    Rate this question:

  • 16. 

    Jumlah pengunjung Kebun Binatang Lestari pada hari senin adalah 14.527 orang dan pada hari selasa adalah 12.187 orang. Jika ditaksir ke ratusan terdekat, maka jumlah pengunjung dua hari tersebut adalah ....

    • 26.500

    • 26.600

    • 26.700

    • 26.800

    Correct Answer
    A. 26.700
    Explanation
    The total number of visitors on Monday is 14,527 and on Tuesday is 12,187. To estimate the total number of visitors for the two days, we round each number to the nearest hundred and add them together. Rounding 14,527 to the nearest hundred gives us 14,500, and rounding 12,187 to the nearest hundred gives us 12,200. Adding these two rounded numbers together, we get 26,700. Therefore, the estimated total number of visitors for the two days is 26,700.

    Rate this question:

  • 17. 

    Taksiran terdekat ke puluhan dari 10.455 + 1.234 – 987 adalah ....

    • 10.500

    • 10.600

    • 10.700

    • 10.800

    Correct Answer
    A. 10.700
    Explanation
    The question asks for the nearest estimate to the tens of the sum of 10,455 + 1,234 - 987. To find this estimate, we need to round the sum to the nearest tens place. The sum of 10,455 + 1,234 - 987 is 10,702. Rounding this to the nearest tens place gives us 10,700, which is the closest estimate to the tens.

    Rate this question:

  • 18. 

    Hasil pembulatan ke ribuan dari operasi hitung 54.398 - 13.895 adalah ....

    • 30.000

    • 39.000

    • 40.000

    • 41.000

    Correct Answer
    A. 40.000
    Explanation
    The correct answer is 40.000. This is because when rounding to the nearest thousand, we look at the digit in the hundreds place. If it is 5 or greater, we round up, and if it is less than 5, we round down. In this case, the digit in the hundreds place is 4, which is less than 5. Therefore, we round down to the nearest thousand, which is 40.000.

    Rate this question:

    Sandi adalah peternak burung yang memiliki jumlah sangkar burung sebanyak 37. Jika setiap sangkar berisi 23 burung, maka kira-kira burung yang dimiliki Sandi adalah ....

    • 700

    • 800

    • 900

    • 1000

    Correct Answer
    A. 800
    Explanation
    Sandi memiliki 37 sangkar burung, dan setiap sangkar berisi 23 burung. Oleh karena itu, jumlah total burung yang dimiliki Sandi dapat dihitung dengan mengalikan jumlah sangkar dengan jumlah burung dalam setiap sangkar. Jadi, 37 x 23 = 851 burung. Namun, pertanyaan meminta perkiraan jumlah burung yang dimiliki Sandi, sehingga jawaban yang paling mendekati adalah 800.

    Taksiran tinggi ke ratusan dari 856 – 443 adalah ....

    • 300

    • 400

    • 500

    • 600

    Correct Answer
    A. 400
    Explanation
    The question asks for an estimate of the hundreds digit of the subtraction 856 - 443. To estimate this, we can round both numbers to the nearest hundred, which gives us 900 - 400. The difference between 900 and 400 is 500, which means the hundreds digit of the subtraction is 5. Therefore, the closest answer choice is 500.

    Rate this question:

    • 150

    • 160

    • 170

    • 180

    Correct Answer
    A. 150
    Explanation
    The question asks for the low estimate of the sum of 84 and 76. To find the low estimate, we round down each number to the nearest ten and then add them together. When we round down 84 to the nearest ten, we get 80, and when we round down 76 to the nearest ten, we get 70. Adding 80 and 70 gives us 150, which is the low estimate of the sum.

    Rate this question:

  • 22.

    • 340

    Correct Answer
    A. 330
    Explanation
    The question asks for the estimated sum of 159 and 163, which is a two-digit number. Looking at the answer choices, we can see that 330 is the only option that fits this criteria. Therefore, 330 is the correct answer.

    • 7.200

    • 8.100

    • 6.400

    • 7.500

    Correct Answer
    A. 7.200
    Explanation
    The correct answer is 7.200 because when you multiply 94 by 87, you get a product of 8,178. However, the question asks for a "taksiran rendah" or a low estimate. Therefore, you round down the product to the nearest hundred, which is 7,200.

    • Rp. 315.000,-

    • Rp. 310.000,-

    • Rp. 312.000,-

    Correct Answer
    A. Rp. 312.000,-
    Explanation
    The correct answer is Rp. 312.000,-. If the total donation collected is Rp. 935.600,- and it will be given to 3 people equally, we can divide the total donation by 3: Rp. 935.600 / 3 = Rp. 311.866,67. Since the question asks for an estimation in thousands, we round up the amount to the nearest thousand, which is Rp. 312.000,-.
