Question

The number of boys varies directly as the number of girls and inversely as the number of teachers. When there are 24 boys and 16 girls, there are 2 teachers. How many girls are there when there are 72 boys and 1 teacher?

Answer 1

SO from what I did was...

Since 24 x 3 = 72 , I did the same to 16.

16 x 3 = 48

But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...

So what I think the answer is...

There are 72 boys, 24 girls, and 1 teacher...

Unless I am just dumb and it would be 48 girls, but I think I did it right.

I hope I was able to help out.
