Answer 1

320 cups of soup.

Explanation:

Given:

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.

Question asked:

How many cups of soup he should prepare ?

Solution:

Ratio of soup appetizer to the number of guest = 2 : 5

Now, let number of cups of soup prepare for 800 guests =
`x`

Now, as we have to find through equivalent ratios, we can write it as:-

2 : 5 =
`x` : 800

`(2)/(5) =(x)/(800) \\\\ By\ cross\ multiplication\\5* x=2*800\\5x=1600\\By\ dividing\ both\ sides\ by\ 5\\x=320`

Thus, he should prepare 320 cups of soup for 800 guests.
