Answer:
Mr. Reed still needs to run 7 5/12 miles to reach his Step-by-step Step-by-step explanation:
2 3/4 and 2 1/3 need to be converted to a common denominator of 12:
2 9/12 and 2 4/12
Then we need to convert the original 12 1/2:
12 6/12
Add the miles he's already run:
2 9/12 + 2 4/12 = 5 1/12
Subtract the total amount run from the total goal:
12 6/12 - 5 1/12 = 7 5/12
Therefore, he still needs to run 7 5/12 miles to meet his total 12 1/2 (or 12 6/12) miles goal.
