Answer: No, he will not meet his goal.

Explanation:

You have to turn the denominator into a common denominator - 6 and 4 can both be multiplied to get 12 (6 by 2 & 4 by 3)

Then you have to multiply the numerator by 2 or 3 (for 1/6 you have to multiply both numbers by 2) (for 1/4 you have to multiply both numbers by 3)

Then you have to add the numbers (which should be 2/12 & 3/12)

So your answer should be only 2 5/12 (which is 1/12 less than needed)
