The best place to start in answering this question is to make all the fractions with the same denominator in order to add them easier.

Therefore, 1 3/4 = 1 9/12, 2 1/3 = 2 4/12, and 1 5/12.

Then you can add them together 1 + 1 + 2 = 4 and then 9/12 + 4/12 + 5/12 = 18/12 or 1 6/12 or 1.5. So he worked a total of 5.5 hours. Then you can multiply his hourly rate by 5.5 to find his total earnings. $10.50 * 5.5 = $57.75
