Question

A salsa recipe uses green pepper, onion, and tomato in the extended ratio 2 : 5: 9. How many cups of onion are needed to make 160 cups of salsa?

Answer 1

50 cups

Explanation:

So rewrite the ratio to be 2x : 5x : 9x

16x = 160

x = 10

5 * 10 = 50

This is only right if the 5 in the ratio is for onions.
