Shasha can mow 3/8 of an acee of grass in 45 minutes. how many acees of grass does shasha mow per hour

To find your answer, divide 3/8 by 3 then add that to 3/8.

This is because there are four 15 minutes in a hour and so there are three 15 minutes in 45 so you must get that other 15.

Hope it helps, tell me if it is too confusing.
