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?

Respuesta :

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

[tex]\begin{gathered} \frac{5}{12}\cdot\frac{3}{5}=\frac{15}{60} \\ \frac{15}{60}=\frac{5}{20}=\frac{1}{4}\text{ Simplifying our fraction} \end{gathered}[/tex]

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