Answer:
He would need to run 5/12 more miles to reach his goal.
Step-by-step explanation:
You want to get all your fractions to the denominator of 12.
1/2 = 6/12
1/4 = 3/12
2/3 = 8/12
Then you would want to add them all up, 6/12+3/12+8/12 = 17/12.
Then you subtract his goal of 22/12-17/12, to get your answer of 5/12.
Hope this helps! :)
