Question

the ratio of black bags to blue bags is 5 to 3. If there are a total of 185 black bags, then how many blue bags are there?

Answer 1

There are 111 blue bags

Explanation:

Let

x ----> the number of black bags

y ---> the number of blue bags

we know that

`(x)/(y)=(5)/(3)`

isolate the variable y

`y=(3)/(5)x` -----> equation A

`x=185` ----> equation B

substitute equation B in equation A

`y=(3)/(5)(185)`

`y=111`

therefore

There are 111 blue bags
