Question

Juan sells 3 oranges for every 2 apples. How many apples should Juan expect to sell

when Juan sells 15 oranges:

Answer 1

He can expect to sell 10 apples

Answer 2

10 apples

Explanation:

We can write a ratio to solve

3 oranges 15 oranges

--------------- = -----------------

2 apples x apples

Using cross products

3x = 2 * 15

3x = 30

Divide by 3 on each side

3x/3 = 30/3

x = 10
