Question

Mrs. killer is making pizza and she uses 20 slices of pepperoni on each pizza how many pepperoni slices will she need to make seven pizzas

Answer 1

To know the answer, we have to build the following relation:

`(x)/(7)=(20)/(1)`

Where x is the number of slices she will need in 7 pizzas. Solving for x:

`x=7\cdot20=140`

Answer: 140 slices of pepperoni
