Answer:
A: 50/80
Explanation:
A ratio will form a proportion with 5/8 when it is equal to 5/8. (A proportion is a statement that two ratios are equal.)
The offered fractions have reduced values of ...
- 50/80 = 5/8 . . . . . the ratio you're looking for
- 40/80 = 1/2
- 55/64 = 55/64
- 50/88 = 25/44
As you can see, only the first answer choice has a value of 5/8, so that is the one that will form a proportion with 5/8:
5/8 = 50/80
