Question

Q. Of the 100 students in 7th grade , 4 out of every 10 students said that pizza

was their favorite food. Based on this, how many students did NOT say pizza was their
favorite food?

Answer 1

You can begin by writing a ratio

4:10

To get the total students to 100, you must multiply 10 by 10. Therefore multiply 10x10 and 4x10

This gives a
40:100 ratio

That is how many said pizza is their favorite

To find how many did not, subtract 100-40 (total-part). This gives 60. That means 60 students didn’t say pizza is their favorite.

60

Hope this helps
