Question

Sophia Isabella share reward of $117 in a ratio of 1 to 8 what fraction of the total reward does Sophia get

Answer 1

Since the ratio is 1:8 that is a total of 9 parts.
Divide $117 by 9 to find the value of EACH part.
117/9 = 13
Sophia gets 1 part so she gets $13
If we needed the amount Isabella received we would multiply 13*8 = $104
Or 117 - 13 = $104
In $ the ratio is $13:$104
