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.

Step-by-step explanation:
*basically ea math game*
uh let's see...
1.3333333333333 mg
X=15
expand the brackets and collect like terms so 6x+15=7x
then -6x to get x=15
