Question

fourteen boys and 21 girls will be equallly divided into groups find the greatest number of groups that cannbe created if no one is left out

Answer 1

There can be 7 groups that can be created with no one left out.

boys = 14
girls = 21

We need to find the factors of each number.
14: 21:
1 x 14 1 x 21
2 x 7 3 x 7

Both have the same factor of 7. So there can be a maximum of 7 groups with 2 boys and 3 girls per group.
