Problema Solution
There are 60 boys and 72 girls in a school. The principal wants to divide the students into gender-specific groups (all boys or all girls) of the largest possible size. Each group needs to have the same number of students. What is the correct size of each group?
Answer provided by our tutors
The greatest common factor for 60 and 72 is 12, since 60 = 5*12 and 72 = 6*12.
