.07 is greater than .007 because .07 is in the hundredths and .007 is in the thousandths.
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes
