### Contoh penggunaan sifat asosiatif pada operasi hitung ( 72 + 54 ) + 93 = ....

• A.

( 72 + 54 ) + ( 72 + 93 )Â

• B.

72 + ( 54 + 93 )

• C.

( 54 + 72 ) + 93

• D.

93 + ( 54 + 72 )Â

B. 72 + ( 54 + 93 )
Explanation
The given expression demonstrates the associative property of addition. According to this property, the grouping of numbers does not affect the sum. In this case, we can rearrange the numbers in any order and still get the same result. The correct answer is 72 + (54 + 93), which means adding 54 and 93 first, and then adding the result to 72.

### Hasil dari 23 x ( 74 + 21 ) sama dengan hasil dari operasi ....

• A.

23 x 74 x 21

• B.

( 23 + 74 ) x ( 23 + 21 )

• C.

74 x ( 23 + 23 )Â

• D.

( 23 + 74 ) + ( 23 x 21 )

D. ( 23 + 74 ) + ( 23 x 21 )
Explanation
The correct answer is ( 23 + 74 ) + ( 23 x 21 ). This is because the given expression is asking for the result of 23 multiplied by the sum of 74 and 21. To solve this, we first calculate 23 x 21, which equals 483. Then, we add 74 to 23, which equals 97. Finally, we add the two results together, resulting in 580.

### 17 x ( 45 – 24 ) = ( 17 x 45 ) - ( 17 x 24 ) Operasi hitung di atas menggunakan sifat .....

• A.

Asosiatif

• B.

Komutatif

• C.

Distributif

• D.

Identitas

C. Distributif
Explanation
The given equation demonstrates the distributive property of multiplication over subtraction. According to this property, when we multiply a number by the difference of two other numbers, it is equal to the difference of the product of the number with each of the two numbers. In this case, 17 is multiplied by the difference of 45 and 24, which is equal to the difference between the product of 17 and 45 and the product of 17 and 24.

### N – 24.651 = 13.609 Bilangan yang tepat untuk menggantikan huruf n adalah ....

• A.

30.320

• B.

38.260

• C.

40.620

• D.

37.250Â

B. 38.260
Explanation
The correct answer is 38.260. To find the value of n, we need to isolate it on one side of the equation. By subtracting 13.609 from both sides, we get n = 24.651 + 13.609 = 38.260. Therefore, 38.260 is the correct value to replace n in the equation.

Rate this question:

• 7.

### 175 jika dibulatkan ke puluhan terdekat menjadi ....

• A.

200

• B.

170

• C.

180

• D.

176

C. 180
Explanation
The question asks for the number 175 to be rounded to the nearest tens. When rounding to the nearest tens, we look at the digit in the ones place. If it is 5 or greater, we round up. If it is less than 5, we round down. In this case, the digit in the ones place is 5, so we round up. Therefore, the nearest tens to 175 is 180.

Rate this question:

• 8.

### Pembulatan ke puluhan berikut ini yang tidak tepat adalah ....

• A.

124 = 120

• B.

326 = 330

• C.

279 = 280

• D.

316 = 330

D. 316 = 330
Explanation
The given numbers are being rounded to the nearest tens place. In all the other examples, the numbers are rounded correctly. However, in the case of 316, it is being rounded up to 330 instead of being rounded down to 310.

### 35.720 jika dibulatkan ke puluhan ribu terdekat menjadi ....

• A.

36.000

• B.

35.700

• C.

35.800

• D.

40.000

D. 40.000
Explanation
The given number, 35.720, needs to be rounded to the nearest ten thousand. Since the digit in the ten thousand place is 7, which is greater than or equal to 5, we round up. Therefore, the number is rounded to 40.000.

Rate this question:

• 10.

### Hasil penaksiran ke ribuan dari penjumlahan 12.345 + 15.610 + 11.199 adalah ....

41.000

• B.

40.000

• C.

39.000

• D.

38.000

C. 39.000
Explanation
The given question asks for the estimated sum of 12,345 + 15,610 + 11,199. The correct answer is 39,000. This can be determined by adding the three numbers together: 12,345 + 15,610 + 11,199 = 39,154. Since the question asks for an estimated sum, we round down to the nearest thousand, which is 39,000.

Rate this question:

### Hasil penaksiran ke ratusan terdekat dari perkalian 237 x 1.467 adalah ....

• A.

300.000

• B.

280.000

• C.

450.000

• D.

420.000

A. 300.000
Explanation
The question asks for the estimated result of multiplying 237 by 1,467. The correct answer is 300,000. This can be determined by rounding 237 to the nearest hundred, which is 200, and rounding 1,467 to the nearest thousand, which is 1,000. Then, multiplying 200 by 1,000 gives the estimated result of 200,000. Since 300,000 is the closest option to 200,000, it is the correct answer.

C. 1, 2, 4, 5, 10, 20, 25, 50 dan 100
Explanation
The factors of a number are the numbers that can be multiplied together to get that number. In this case, the factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. These numbers can be multiplied in different combinations to equal 100. Therefore, the correct answer is 1, 2, 4, 5, 10, 20, 25, 50, and 100.

• C.

2 x 5 x 5 x 10

• D.

2 x 5 x 5 x 5 x 5Â

A. 2 x 2 x 5 x 5 x 5
Explanation
The prime factorization of 500 is 2 x 2 x 5 x 5 x 5. This means that 500 can be expressed as the product of these prime numbers. The number 2 appears twice, and the number 5 appears three times. Therefore, the correct answer is 2 x 2 x 5 x 5 x 5.

• A.

120

• B.

45

• C.

60

• D.

90

C. 60
Explanation
The KPK (Least Common Multiple) of 12, 15, and 30 is the smallest number that is divisible by all three numbers. To find the KPK, we can list the multiples of each number and find the smallest number that appears in all three lists. The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, ... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, ... The multiples of 30 are 30, 60, 90, 120, ... The smallest number that appears in all three lists is 60, so the KPK of 12, 15, and 30 is 60.

• C.

24

• D.

16

C. 24
Explanation
Bus Jaya Sentosa lewat setiap 8 jam sekali dan bus Sejati Raya lewat setiap 12 jam sekali. To find the time when both buses will pass together, we need to find the least common multiple (LCM) of 8 and 12. The LCM of 8 and 12 is 24. Therefore, Bus Jaya Sentosa and bus Sejati Raya will pass together every 24 hours.

A. 26 Maret 2018
Explanation
Santi berenang setiap 4 hari sekali, sedangkan Siska berenang setiap 6 hari sekali. Jika mereka terakhir kali berenang bersama pada tanggal 2 Maret 2018, maka Santi akan berenang lagi pada tanggal 6 Maret 2018, 10 Maret 2018, 14 Maret 2018, dan seterusnya. Siska akan berenang lagi pada tanggal 8 Maret 2018, 14 Maret 2018, 20 Maret 2018, dan seterusnya. Jadi, mereka akan berenang bersama-sama pada tanggal 26 Maret 2018.

• D.

10

B. 5
Explanation
The maximum number of jars the mother can use is 5. This can be determined by finding the greatest common divisor (GCD) of 30 and 35, which is 5. The GCD represents the largest number of items that can be evenly divided into both quantities. Therefore, the mother can use 5 jars to distribute the 30 chocolate bread and 35 cheese bread equally.
