Question

A soup recipe uses noodles, cheese, and potatoes in the extended ratio 4:5:7. How many cups of cheese are needed to make 192 cups of soup?

Answer 1

Answer: 60 cups of cheese

Explanation:

noodles:cheese:potatoes

4:5:7

192 total cups of soup

each unit of recipe is 4+5+7=16

so divide total cups of soup by one recipe unit

192/16=12

This means 12 recipe units were used. So each value from ratio 12 times...

4:5:7 = one unit of soup (16 cups)

48:60:84 = 12 units of soup (192 cups)

So 60 cups of cheese are needed for 192 cups of soup.
