Question

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.

Answer 1

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

Answer 2

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
