It takes 3 hours to wash every window on a building. There are 30 windows. How many windows does it take to wash each window?


3 hours = 180 minutes

= 180 minutes / 30 windows

= 6 minutes


This is my work but I am not sure if it is right. Please check over.

Your work is correct. 3hours=180min 180÷30=6

3hours=all
all=30windows
3hours=30windows
3hours=3 times 60mins=180mins
180mins=30windows
divide both sides by 30
6mins=1window
