Question

28 girls and 32 boys volunteer to plant trees at a school. the principal divides the girls and boys into identical groups that have girls and boys in each group. what is the greatest number of groups the principal can make?

Answer 1

4 groups

Explanation:

The question asks, "What is the greatest number of groups the principal can make?" so, you have to find the GCF (Greatest Common Factor)

28: 1, 2, 4, 7, 14, 28

32: 1, 2, 4, 8, 16, 32

As you can see, 4 is the greatest common factor here.

So, the greatest number of groups that the principal can make is 4 groups.

Answer 2

The answer will be the biggest number, by which you can divide both 28 and 32. So you can divide them in 4 groups (28/4=7 girls per group & 32/4=8boys per group)
