There are 90 girls and 60 boys Participating in a race. The coach separates them into two equal groups made of all girls or or boys. What is the greatest number of students possible for each group?
90/2 is 45.. 60/2 is 30.. 30+45=75... 75 students would be able to be in each of the 2 groups, each containing 45 girls and 30 boys ... Hope I helped (:
