Answer:
7 5 /12 miles
Step-by-step explanation:
We need to determine how many miles he has run so far
Monday 2 3/4
Tuesday 2 1/3
----------------------------
Total 4 + 3/4 + 1/3
Getting a common denominator
4 + 9/12 + 4/12
4 13/12
4 12/12 + 1/12
5 1/12
He has run 5 1/12 miles
His goal is 12 1/2 miles. We need to subtract 5 1/12 from 2 1/2
Getting a common denominator
12 6/12 - 5 1/12
7 5 /12 miles
