Agroup of workers can plant 6 3/4 acres in 1 7/8 days. what is the unit rate in acres per day?

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

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