Question

kelsey and her 4 sisters spent equal amount of time cleaning their home. their parents added their times. they found that each of the girls spent 3 hours cleaning. let c be the total number of hours the girls spent cleaning. write and solve a division equation to find the total number of hours the girls spent cleaning

Answer 1

Let:

`\begin{gathered} x=\text{ Time spent by every sister} \\ x+x+x+x+x=3 \\ (3)/(5)=c \\ c=\text{total number of hours the girls spent cleaning} \end{gathered}`

Solving for c:

`\begin{gathered} (3)/(5)=c \\ \text{ Solve for }c\colon \\ (3)/(5)=0.6 \\ c=0.6h=36\min \end{gathered}`

Answer:

36 minutes
