Question

Maureen went on a 3 day 50 mile trip. the first day she biked 17 7/8 miles . the second day she biked 18 5/7 miles. How many miles did she biked in 3rd day

Answer 1

To find the miles for 3rd day, we take away the miles she biked for the first two day from the total.


`50 - 17 (7)/(8) - 18(5)/(7)`


`=50 - 17 (7 * 7)/(8 * 7) - 18(5 * 8)/(7 * 8)`


`= 48 (112)/(56) - 17 (49)/(56) - 18(40)/(56)`


`= 13 (23)/(56) \text { miles }`

Answer: She traveled 13 23/56 miles on the third day.
