Answer: D. 3 15/20 - 1 4/20
Step-by-step explanation:
3 3/4 and 1 1/5
both 4 and 5 go into 20, so you can make 20 your common denominator
3/4 * 5/5 = 15/20
1/5 * 4/4 = 4/20
now you have 3 15/20 and 1 4/20
since the total distance = 3 15/20 and the distance he has already
run = 1 4/20, so you subtract the value to find what he has left.
3 15/20 - 1 4/20 = how many miles left
