Joe Jackson worked 8 hours on Monday, 4 1/4 hours on Tuesday, 6 1/8 hours on Wednesday, 7 1/4 hours on Thursday, and 8 1/8 hours on Friday. Calculate the total number of hours Joe worked for the week.

First thing you are going to need to do is get all the fractions to have the same denominator.

You would turn all the fractions that have 1/4 into 2/8

This turns the times into this ...

Monday - 8

Tuesday - 4 2/8

Wed. - 6 1/8

Thurs. - 7 2/8

Friday - 8 1/8

Now you need to add these all together

8 + 4 2/8 + 6 1/8 + 7 2/8 + 8 1/8

This turns into

33 6/8 Hours

The total number of hours that Joe worked for the week is 43 3/4 hours
