A classmate read 99 pages in 3 days. What's the unit rate?

to find the unit rate we need to find how many pages he reads each day.

We divide 99/3 to find the amount he read in one day.

99/3 = 33

A classmate read 33 pages per day.

99 pages/3 days = 33 pages/day

3 days / 99 pages = 1/33 days/page

33 pages per day
