A group of workers can plant 6 3/4 acres in 1 7/8 days. What is the unit rate in acres per day?
Sedaia [141]

Answer:

The answer is 3.6 acres per day

Step-by-step explanation:

To find the unit rate divide the number of acres by number of days

∴ Unit rate = 6\frac{3}{4} ÷ 1\frac{7}{8}

                  = (6 × 4 + 3)/4 ÷ (1 × 8 + 7)/8 = 27/4 ÷ 15/8

                  = 27/4 × 8/15 = 18/5 = 3.6 acres per day
