Question

If you can buy 4⁄5 of a pound of ham for 3 dollars, how much can you purchase for 10 dollars? Write your answer as a fraction of a pound.

Answer 1

8/3

Explanation:

Use ratios and the rule of three.

A : B

? : D

In this case you will always multiply D by A and divide it by B to find the unknown. Now just apply this to our question.

4/5 lbs : $3

? : $10

10 * 4/5 = 8

8÷3 = 8/3
