The ration of boy campers to total campers is 8:15, and the ratio of girl campers to total campers is 7:15. Using this information, we can answer this question by setting up proportions.
For boys:

*Cross multiply*
15x=1560
*Divide both sides by 15*
x=104
There are 169 boy campers.
For girls:

*Cross multiply*
15x=1365
91=x
There are 91 girl campers.
Hope this helps!!
