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

1 answer:

3 0

Answer: 192 pounds.

Step-by-step 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 :-

$\dfrac{x}{168}=\dfrac{8}{7}\\\\\Rightarrow\ x=\dfrac{8\times168}{7}\ \ \text{[Multiply 168 on both sides]}\\\\\Rightarrow\ x=8\times24=192$

Therefore, the weight of Frances = 192 pounds.
