9/10 of the pizzas at a pizza shop were hawaiian pizzas. the rest of the pizzas were vegetarian pizzas. there were 72 more hawaiian pizzas than vegetarian pizzas. how many pizzas were there in all?

90 pizzas

Step-by-step explanation:

We know that 9/10 of the pizzas are Hawaiian, and the other 1/10 are vegetarian. There are 72 more Hawaiian pizzas than vegetarian pizzas. It's the 72 that's important here. We know 9/10 are Hawaiian and the other tenth are vegetarian. Subtract 1/10 from 9/10 to get 8/10.

(9 - 1)/10

8/10

As a result, 72 is 8/10 of the total. Now divide 72 by 8/10. That is the same as 72 times 10/8.

72 / 8/10

72/1 * 10/8

9/1 * 10/1

9 * 10

There are 90 total pizzas in the pizza shop.
