Question

robin can clean 72 rooms in 6 days how many rooms can she clean in 9 days

Answer 1

she can clean  72/6 = 12 rooms in one day
So in 9 days she can clean 9*12 = 108 rooms.

Answer 2

It looks like she is going at a rate of about 12 rooms a day. (72/6=12 rooms per day)

So to figure out how many rooms she can clean in nine days all we have to do is take her rate per day (12) times how many days she has to clean (9) which equals 108 rooms being able to be cleaned in the given time period.
