Answer:
30 slices
Step-by-step explanation:
Make a proportion
You ate 5 out 20 slices, and x out of 120 slices
5/20=x/120
Multiply both sides by 120 to get x by itself
120(5/20)=(x/120)120
The 120s on the right will cancel out, and we are left with
30=x
So, you would eat 30 slices of pizza out of 120 slices
