Question

10. Mr. Schmidt's classes combined have 42 boys and 56 girls. He wants to divide them up into

equal groups with the same number of boys and girls in each group. What is the greatest number
of groups? How many boys and girls are in each group? (3pts.)
a.) number of groups_
b.) number of girls
c.) number of boys

Answer 1

A: 7

B: 8

C: 6

Explanation:

You have to try to find the the same greatest factor of both of the numbers.

Since both of the numbers are divisible by 7 the number of groups equals 7.

So you divide the number of girls, which is 56, by 7, the number of girls in each group is 8.

Then you divide the number of boys, which is 42, by 7, the number of boys in each group is 6.
