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?
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)
Answer:
4 groups
Step-by-step 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.
