Question

A salsa recipe uses green pepper, onion, and tomato in a ratio of 2 : 5 : 8. How many cups of onion are needed to make 60 cups of salsa? (Show work)

Answer 1

Answer:

20 cups of onion

Step-by-step explanation:

If your ratio of pepper:onion:tomato is 2:5:8, add up those numbers to get 15.  Onion exists in this ratio as 5cups onion/15cups salsa.  We need to know how much onion in 60cups.  Set up the proportion like this:

$\frac{5}{15}=\frac{x}{60}$

Cross multiply to get 15x = 300 and x = 20.  If you do the same with the other ingredients, you'll add them together in the end to get a total of 60 cups.
