I think the the problem is trying to say the ratio is 3:5 and somehow it just got doubled up.

So the ratio is 3:5. That means there are 3 + 5 portions, or 8 portions.

If you can thing of a better word than portions, then use it.

Divide 120,120 by the total number of portions 120,120 / 8 = 15,015

So each portion is 15,015 and the adults have 5 of them. 15,015 • 5 = **75,075 adults**

3/5 = 120/adults

I think the 3:5 doubled up and I think the 120 doubled up. I don't know why it would do that.

So 3 / 5 is the ratio and there are 120 children

3 / 5 = 120 / x

cross multiply 3 • x = 5 • 120

3x = 600

x = **200 Adults**
