Of a group of students 5/8 of them are boys. The girls are put into groups so that each group has 1/6 of the total number of students. How many groups of girls are there?

Answer 1

Let's say there are x students in total.
Clearly 3/8 of the students are girls.

So, if there are n groups of girls, we have

n(x/6) = (3/8)x
4nx = 9x
4n = 9
I don't see any way to divide the girls evenly.

Did I miss something?
