Question

kelsey and her 4 sisters spent an equal amount of time cleaning their home. their parents added their times. they found that each of the 5 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:

x = amount of time spent by every girl

n = number of girls = 5

their parents added their times. they found that each of the 5 girls spent 3 hours cleaning, so:

$\begin{gathered} x=3 \\ 3=\frac{c}{n} \\ \end{gathered}$

c = the total number of hours the girls spent cleaning

$\begin{gathered} \text{Solve for c:} \\ c=3\times n \\ c=3\times5 \\ c=15h \end{gathered}$
