21/2 or 10 1/2
Explanation:
8 3/4 is the same as 35/4
so Darcy harvests 35/4 per 5/6 hours
to figure out how much is harvested in one hour, you divide the amount harvested by the amount of hours taken to harvest it.
35/4 ÷ 5/6 =35/4 × 6/5
35/4 × 6/5 = 7/2 × 3/1 = 21/2
so the answer is 21/2 or 10 1/2
