Answer:
3 squares/hour
Explanation:
We want a rate expressed in quares/hour. The only measurement we have is 3/4 of a square in 2/8 hour. The units are squares and hours, so divide the 3/4 square by 2/8 hour to get:
(3/4 square)/(2/8 hour)
(3/4)*(8/2) squares/hour
(24/8) squares/hour
3 squares/hour
