Question

3. The 7th grade students took a survey about which pizza company the students

preferred: Papa John's, Dominos or Pizza Hut. There are 64 students in the 7th

grade.

If 5 out of 8 students chose Papa John's, how many students chose Papa

John's? How many did not?

Answer 1

40 students choose Papa John's, and 24 did not

Explanation:

This question can be solved by proportions, using rule of three.

For each 8 students, 5 chose Papa John's. Out of 64, how many choose?

5 - 8

x - 64

Applying cross multiplication

`8x = 5*64`

Simplifying by 8

`x = 5*8 = 40`

40 students choose Papa John's.

In all, there are 64 students, so 64 - 40 = 24 did not
