Question

Lucy sold some items at a garage sale. She spent 7/12 of her earnings on a new bike. She uses 3/5 of the remainder to purchase a gift for her mom. What traction of her total earnings was spent on her mom's gift?

Answer 1

First we have to find the fraction that represents the remainder after buying the bike, subtracting 7/12 from the total, represented by 12/12

The result is 5/12

Then we have to multiply 5/12 by 3/5 to find our final answer

`\begin{gathered} (5)/(12)\cdot(3)/(5)=(15)/(60) \\ (15)/(60)=(5)/(20)=(1)/(4)\text{ Simplifying our fraction} \end{gathered}`

The fraction of her total earnings spent on her mom's gift was 1/4
