Question

Mateo ate 3/8 of a pizza, which was a total of 510 calories of food. Which equation can be used to determine the total number of calories in the entire pizza?

Answer 1

Usually a pizza has 8 slices. 3/8 of 8 = 3.
So eating 3 pieces was 510 calories. Divide 510/3.
510/3 = 170.
Then there are 8 pieces of pizza.
170 * 8 = 1360
There are 1360 calories in the pizza.

Hope this helps you! (:
