Aclass of 20 boys and 15 girls is divided into n groups so that each group has x boys and y girls. find x, y and n. what values are referred in this class

20 = 2 x 2 x 5
15 = 3 x 5

common divisor (CD) of 20 and 15 is 5 so n should be 5 and each group has 4 boys and 3 girls.

If there are more than one CD, then there are more than one answer.

If they ask for the largest number of groups, greatest common divisor (GCD) will be the answer.

Idon’t know what the answer is i wish i could
