Question

At Pizza Pi, 95% of the pizzas made last week had extra cheese. If 19 pizzas had extra cheese, how many pizzas in all were made last week?

Answer 1

95÷19=5

5%= 1 pizza

100%=20 pizzas

Answer 2

If you would like to know how many pizzas in all were made last week, you can calculate this using the following steps:

95% of x = 19
95/100 * x = 19 /*100
95 * x = 19 * 100 /95
x = 19 * 100 / 95
x = 20

Result: 20 pizzas were made last week.
