Question

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

Answer 1

320 coups of soup

Explanation:

The number of guests he expects is 800, and he thinks that 2 out of every 5 guests will order soup. So, to estimate how many cups of soup he should prepare, we can do a rule of three:

For every 5 guests, 2 will order soup, so for 800 guests, X soups will be ordered.

5 guests -> 2 soups

800 guests -> X soups

5/800 = 2/X

X = 800 * 2 / 5 = 320

He should prepare 320 coups of soup.

Answer 2

Cups of soup to be prepared = 320

Explanation:

Using equivalent ratios

2:5 = X:800

X = (800 x 2)/5 = 320 cups

Cups of soup to be prepared = 320
