### Last summer, at Camp Okey-Fun-Okey, the ratio of the number of boy campers to the number of girl campers was 8:7.

If there were a total of 195 campers, how many boy campers were there?
How many girl campers?

First, we're going to add the two ratios.
This is our 8+7=15.
We now divide 195 (total campers) by 15, to make individual copies of our ratio.
195/15=13.
We can fit our ratio, 8:7, into 195 13 times.
We now multiply both numbers by 13 for the exact number of campers.
8x13=104, and 7x13=91.
We can check our math by adding the two final numbers.
104+91=195.
Since our number matches the total number of campers, we know it is correct.
There are 104 boy campers and 91 girls.
