• The constant rate is 1/3 acre per every 3/4 hour.

To find the fraction that represents the constant per hour, we just need to divide both expression, like this

`(1)/(3)acre / (3)/(4)hr=(1)/(3)* (4)/(3) =(4)/(9)acres/hr`

Therefore, the expression that represents the acres Jack can mow per hour is

`(4)/(9)acres/hr`
