Question

The ratio between Frances and Carolina's weight is 8: 7, if Carolina weighs 168 pounds, how much does Frances weigh?

Answer 1

Answer: 192 pounds.

Explanation:

Let x denotes the weight of Frances ( in pounds ).

Given : The ratio between Frances and Carolina's weight is 8: 7

If Carolina weighs 168 pounds, then using proportion s we have the equation below :-

`(x)/(168)=(8)/(7)\\\\\Rightarrow\ x=(8*168)/(7)\ \ \text{[Multiply 168 on both sides]}\\\\\Rightarrow\ x=8*24=192`

Therefore, the weight of Frances = 192 pounds.
