The recipe for mint chocolate ice cream requires 2 1/4 cups of creams for 5 people. You need ice cream for 8 people. How much cream will you need?
Please explain,thanks.

2 1/4 = 9/4
(9/4)(8/5) = (9/1)(2/5) = 18/5 = 3 3/5 cups 
Let's set up a proportion and crossmultiply.
2 1/4 / 5 = x / 8
5x = 2 1/4 * 8
5x = 18
x = 3 3/5 cups 
3.6

3 3/5 cups idk why it's 2016 In my school still got us doing this

2 1/4 รท 5 = 9/20
9/20 x 8 = 18/5
18/5 = 3.6
3.6 cups
