Shara works 7/40 day, 5 days a week. Saul works 7/80 week each week. Find the number of hours each person works each week as a decimal. Which person works for the greater amount of time each week?

7/40 a day means that Shara works (7/40)*24=4.2 hours a day.

Multiplying 4.2 by 7, we get 29.4 hours per week, so Shara works 29.4 hours per week

 

Saul works 7/80 week each week

There are 168 hours in a week, so we multiply 7/80 by 168 to get 14.7 hours per week

 

Shara works more than Saul each week

Shara works 29.4 hours a week and Saul works 14.7 hours a week

 

Let me know if I did anything wrong laugh

You did do something wrong frown

 

Shara works 5 days a week so it should be 4.2*5 but you did 4.2*7

Oops!

 

so the answer for Shara is actually

 

4.2x5 = 21 hours per week for Shara

7/40 day  * 24 hr/day * 5 days = 21 hrs per week for Shara

 

7/80 wk   x 7 day/week  x 24 hr/day= 14 .7 hrs per week for Saul
