Explanation
The correct answer is 16. To find the percentage of 4/25, we need to divide 4 by 25 and then multiply by 100. 4 divided by 25 is 0.16, and when multiplied by 100, we get 16%.

Explanation
20% of 5,000 is calculated by multiplying 5,000 by 0.20. This gives us 1,000, which is the correct answer.

Explanation
The percentage of rotten oranges can be calculated by dividing the number of rotten oranges (12) by the total number of oranges (60) and then multiplying by 100. Therefore, the percentage of rotten oranges is (12/60) * 100 = 20%.

Explanation
The correct answer is 7/10 because when the number 35 is divided by 100, it simplifies to 7/10. This is because both 35 and 100 can be divided by 5, resulting in 7/10, which is the simplest form of the fraction.

Explanation
The correct answer is 8/20 ; 0,3 ; 0,25 ; 20%. This is the correct order because 8/20 is the largest fraction among the options given. Then, 0.3 is the next largest decimal number. After that, 0.25 is the next smallest decimal number. Finally, 20% is the smallest percentage among the options.

Explanation
The length of Puput's ribbon is 2 3/8 meters, the length of Luki's ribbon is 6/8 meters, and the length of Putri's ribbon is 5/8 meters. To find the total length of the three ribbons, we add them together: 2 3/8 + 6/8 + 5/8 = 3 3/4. Therefore, the correct answer is 3 3/4.

Explanation
The given expression is a sum of fractions with different denominators. To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 30. We can then rewrite the fractions with the common denominator and add the numerators.

2/5 is equivalent to 12/30 (multiplied numerator and denominator by 6), 2/3 is equivalent to 20/30 (multiplied numerator and denominator by 10), and 5/6 remains the same.

Adding the numerators, we get 12/30 + 20/30 + 5/6 = 37/30.

Since 37/30 is an improper fraction, we can simplify it to a mixed number. Dividing 37 by 30, we get 1 with a remainder of 7. Therefore, the answer is 1 7/30.

Explanation
The question states that today the father picked 1/4 quintal of mangoes and yesterday he picked 1.2 quintal. Then he sold 1/2 quintal. To find the remaining mangoes, we need to subtract the amount sold from the total amount picked.
Yesterday: 1.2 quintal - 1/2 quintal = 1.2 - 0.5 = 0.7 quintal
Today: 1/4 quintal
Total remaining: 0.7 quintal + 1/4 quintal = 0.7 + 0.25 = 0.95 quintal
0.95 quintal can be written as 9/10 quintal, which is equivalent to 9/20. Therefore, the correct answer is 9/20.

Explanation
The given expression is a division operation between 1.4 and 0.2. When 1.4 is divided by 0.2, the result is 7. Therefore, the correct answer is 7.

Explanation
Pak Badrus memiliki hasil panen sebesar 5 1/3 ton. Setiap anak akan mendapat bagian sebesar 4/3 ton. Untuk mengetahui berapa banyak anak yang akan mendapatkan bagian tersebut, kita perlu membagi total hasil panen dengan bagian yang akan diterima setiap anak. Jadi, 5 1/3 ton dibagi dengan 4/3 ton akan menghasilkan 4 anak.
