To find out how much Fred earned, you need to calculate the total number of hours he worked during the week and then multiply that by his hourly wage.

Fred's hours: 8 hours + 4 1/2 hours + 3 3/4 hours + 7 1/2 hours + 4 3/4 hours

First, convert all the mixed numbers to improper fractions: 4 1/2 = 4 + 1/2 = 9/2 3 3/4 = 3 + 3/4 = 15/4 7 1/2 = 7 + 1/2 = 15/2 4 3/4 = 4 + 3/4 = 19/4

Now add up all the hours: 8 + 9/2 + 15/4 + 15/2 + 19/4

To add these fractions, you need a common denominator, which is 4: 8 = 32/4 9/2 = 18/4 15/4 stays the same 15/2 = 30/4 19/4 stays the same

Now add: 32/4 + 18/4 + 15/4 + 30/4 + 19/4 = 114/4 = 28.5 hours

Fred worked a total of 28.5 hours.

To find out how much he earned, multiply the total number of hours by his hourly wage: 28.5 hours × $5.15/hour =$146.78

Fred earned $146.78.
