If your at a camp with 195 kids but the ratio is 7 girls to 8 boys how many boy's are there?

8 boys to 7 girls. You can also say 8 boys out of 15 campers.

8:15::x:195

8*195 = 15x

1560 = 15x

104 = x

In the given question, there are several information's that are worth noting. based on these information's the correct answer can be easily deduced. The ration of girls to boys is given as 7:8. the total number of kids in the camp is 195.

Let us assume the common ratio = x

then

7x + 8x = 195

15x = 195

x = 195/15

= 13

Now it would be easy to find the number of boys in the camp.

Number of boys in the camp = 8 * 13

= 104

So there are a total of 104 boys among the 195 kids in the camp
