Question

How to do this? I am extremely confused.

Answer 1

Answer:

13. 3/4 = 75/100 = 75%

14. 1/2 = 50/100 = 50%

15. 17/20 = 85/100 = 85%

16. 13/25 = 42/100 = 42%

Step-by-step explanation:

For this question, you do the opposite of what you did in the other problem. You put the percentage over a denominator of 100. For example,

75 ⇒ 75/100

50 ⇒ 50/100

85 ⇒ 85/100

Then, to find the reduced fraction, you cross-multiply to find the numerator of the fraction.

75 × 4 = 300 / 100 = 3 ⇒ 3/4

50 × 2 = 100 / 100 = 1 ⇒ 1/2

85 × 20 = 1700 / 100 = 17 ⇒ 17/20

To solve #16, please reference back to my explanation from the other question.

Answer 2

Essentially, it seems the teacher wants you to convert fractions to a percentage. For number 13, you would look at the percentage which is 75%, and then try and find an equal fraction (3/4, 75/100). #14: 1/2, 50/100 #15: 17/20, 85/100 #16: 13/25 is equal to 0.52, so that means it would be 52/100 and 52%.
