60 people can receive a single slice of pizza,how many people can receive a single slice of pizza if 7 pizzas are purchased?

9 slices to a pizza

To solve this problem, we need to find the total number of people who can receive a single slice of pizza when 7 pizzas are purchased.

Given that 60 people can receive a single slice of pizza, we can use the proportion:

"60 people is to 1 pizza slice as X people is to 7 pizzas"

We can set up the proportion as follows:

60 / 1 = X / 7

To solve for X, we can cross-multiply:

60 * 7 = 1 * X

420 = X

Therefore, when 7 pizzas are purchased, 420 people can receive a single slice of pizza.
