Question

how many restaurants have hawaiin pizza on their menu if 7.5% of the 100 restaurants served hawaiin pizza

Answer 1

By my, calculations this means that there is an estimated number of restaurants that receive a Hawaiian pizza order from their menu and that is 7.5. So out of 100 restaurants, there are 7.5 Hawaiian pizza orders. 

Answer 2

There are 7.5 Hawaiian pizza orders. Remember that if there is something that is out of 100 it will always be the number of the percent.
