Question

2 A chef planning for a large banquet

thinks that 2 out of every 5 dinner
guests will order his soup appetizer.
He expects 800 guests at the banquet.
Use equivalent ratios to estimate how
many cups of soup he should prepare.

Answer 1

320

Explanation:

2 out of 5 is the ratio 2/5.

We want the denominator to become 800.

`(800)/(5) = 160`

`160 * 2 = 320`

`(2)/(5) = (2 * 160)/(5 * 160) = (320)/(800)`

Since 2/5 = 320/800, he will need to prepare 320 cups of soup.
