A. Pembilang
Explanation
In fractions, the number that is located above the line is called the "pembilang" or numerator. It represents the number of equal parts being considered or counted. The numerator is divided by the denominator (penyebut) to determine the value of the fraction. The numerator and denominator together form the fraction.

• B.

Seperdelapan

• C.

Delapan satu

• D.

Delapan persatu

B. Seperdelapan
Explanation
The correct answer is "Seperdelapan." This is because the word "seper" means "one" in Indonesian, and "delapan" means "eight." Therefore, when combined, "seperdelapan" translates to "one eighth" in English, which accurately represents the fraction 1/8.

D.  3⁄4
Explanation
The simplest form of 75/100 is 3/4 because both the numerator and denominator can be divided by 25. When we divide 75 by 25, we get 3, and when we divide 100 by 25, we get 4. Therefore, the fraction 3/4 is the simplest form of 75/100.

• B.

15⁄36

• C.

36⁄15

• D.

12⁄15

A. 15⁄12
Explanation
The given expression represents the sum of three fractions: 10/12, 4/12, and 1/12. To add these fractions, we need to have a common denominator. In this case, the common denominator is 12. Adding the numerators of the fractions and keeping the denominator the same, we get 10+4+1=15. Therefore, the sum of these fractions is 15/12.

3⁄8  + 2⁄3  = .... Hasil dari penjumlahan pecahan di atas adalah ....

• A.

5⁄24

• B.

5⁄11

• C.

25⁄24

• D.

6⁄24

C. 25⁄24
Explanation
When adding fractions, we need to have a common denominator. In this case, the common denominator is 24. So, we need to convert both fractions to have a denominator of 24.

To convert 3/8 to have a denominator of 24, we multiply the numerator and denominator by 3, resulting in 9/24.

To convert 2/3 to have a denominator of 24, we multiply the numerator and denominator by 8, resulting in 16/24.

Now, we can add the fractions: 9/24 + 16/24 = 25/24.

Therefore, the correct answer is 25/24.

Rate this question:

1⁄4  + 1⁄2  + 2⁄5 = .... Hasil dari penjumlahan pecahan di atas adalah ....

• A.

4⁄11

• B.

23⁄20

• C.

4⁄20

• D.

2⁄40

B. 23⁄20
Explanation
The given expression involves adding three fractions together. To add fractions, we need to find a common denominator. In this case, the common denominator is 20.

Converting the fractions to have a denominator of 20, we get:

1/4 = 5/20
1/2 = 10/20
2/5 = 8/20

Adding these fractions together, we get:

5/20 + 10/20 + 8/20 = 23/20

Therefore, the correct answer is 23/20.

Rate this question:

• 16.

21⁄25 - 10⁄25  - 8⁄25  = .... Hasil dari pengurangan pecahan di atas adalah ....

• A.

3⁄25

• B.

13⁄25

• C.

29⁄25

• D.

3⁄0

A. 3⁄25
Explanation
The given expression involves subtracting fractions with a common denominator of 25. By subtracting the numerators and keeping the denominator the same, we get 21/25 - 10/25 - 8/25 = (21 - 10 - 8)/25 = 3/25. Therefore, the correct answer is 3/25.

Rate this question:

• 17.

3⁄4  - 2⁄3  = .... Hasil dari pengurangan pecahan di atas adalah ....

• A.

3⁄12

• B.

4⁄12

• C.

1⁄12

• D.

1⁄1

C. 1⁄12
Explanation
The given question asks for the result of subtracting the fractions 3/4 and 2/3. To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12. We can convert 3/4 to 9/12 and 2/3 to 8/12. When we subtract 8/12 from 9/12, we get 1/12 as the result.

Rate this question:

• 18.

2⁄5  + 3⁄6  - 7⁄10 = .... Hasil dari operasi hitung pecahan di atas adalah ....

• A.

5⁄30

• B.

6⁄30

• C.

7⁄30

• D.

8⁄30

B. 6⁄30
Explanation
The given expression involves adding and subtracting fractions. To do this, we need to find a common denominator for all the fractions involved. In this case, the common denominator is 30.

Converting each fraction to have a denominator of 30, we get 12/30 + 15/30 - 21/30.

Now, we can add and subtract the numerators while keeping the common denominator.

12/30 + 15/30 - 21/30 = (12 + 15 - 21)/30 = 6/30.

Therefore, the correct answer is 6/30.

Andi membuat tongkat sepanjang 1 1⁄2 meter dan Santoso membuat tongkat sepanjang 2 1⁄4 meter. Total panjang tongkat mereka berdua adalah .... meter

• A.

3 1⁄4

• B.

3 1⁄2

• C.

3 3⁄4

• D.

3 2⁄4

C. 3 3⁄4
Explanation
Andi membuat tongkat sepanjang 1 1/2 meter, yang dapat ditulis sebagai pecahan 3/2. Santoso membuat tongkat sepanjang 2 1/4 meter, yang dapat ditulis sebagai pecahan 9/4. Untuk menentukan total panjang tongkat mereka berdua, kita perlu menjumlahkan kedua pecahan ini. Dalam hal ini, kita perlu menemukan pecahan yang memiliki penyebut yang sama. Penyebut terkecil yang dapat digunakan adalah 4. Jadi, pecahan 3/2 dapat ditulis sebagai 6/4 dan pecahan 9/4 tetap sama. Sekarang kita dapat menjumlahkan kedua pecahan ini, yang menghasilkan pecahan 15/4 atau 3 3/4. Oleh karena itu, total panjang tongkat mereka berdua adalah 3 3/4 meter.

• C.

Rp. 5.000,00

• D.

Rp. 7.500,00

D. Rp. 7.500,00
Explanation
Budi menggunakan 1/4 bagian dari uangnya untuk membeli es jeruk. Jadi, uang yang digunakan adalah 1/4 x Rp. 10.000,00 = Rp. 2.500,00. Sisa uang Budi sekarang adalah Rp. 10.000,00 - Rp. 2.500,00 = Rp. 7.500,00.

Bentuk pecahan biasa dari 0,625 adalah ....

• A.

3⁄8

• B.

4⁄8

• C.

5⁄8

• D.

6⁄8

C. 5⁄8
Explanation
The correct answer is 5/8 because when we convert the decimal 0.625 into a fraction, we can see that it is equivalent to 5/8. To convert the decimal into a fraction, we can write it as 625/1000 and then simplify it by dividing both the numerator and denominator by their greatest common divisor, which is 125. This gives us 5/8 as the simplest form of the fraction.

Rate this question:

• 24.

Bu Santi membeli 1⁄2 kg tepung terigu, 2,5 kg beras dan 1 1⁄4 kg telur. Total  berat belanjaan Bu Santi adalah ....

• A.

4,20 kg

• B.

3,75 kg

• C.

4,25 kg

• D.

5,5 kg

C. 4,25 kg
Explanation
Bu Santi bought 1/2 kg of flour, 2.5 kg of rice, and 1 1/4 kg of eggs. To find the total weight of her purchases, we need to add these amounts together. Converting the mixed fraction to a proper fraction, we have 1 1/4 = 5/4. So, the total weight is 1/2 + 2.5 + 5/4 kg. Adding these fractions, we get 1/2 + 10/4 + 5/4 = 2/4 + 10/4 + 5/4 = 17/4 kg. Simplifying this fraction, we get 4 1/4 kg, which is equivalent to 4.25 kg. Therefore, the correct answer is 4.25 kg.
