Fred worked these hours during the week: #8, 4 1/2, 3 3/4, 7 1/2, 4 3/4#. If he is paid $5.15 per hour, how much did he earn?

total number of hours worked is

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.

To calculate Fred's earnings:

1. Add up the hours worked: 8 + 4 1/2 + 3 3/4 + 7 1/2 + 4 3/4 = 28.5 hours
2. Multiply the total hours worked by his hourly rate: 28.5 hours * $5.15/hour =$146.775
3. Round the amount to the nearest cent: $146.78 Therefore, Fred earned$146.78.
