Tom reads 10 hours over 5 days.  He can read 50 pages per hour.  Assuming he reads the same amount every day how many pages does he read in 7 days?
He reads 10/5=<T>divide(10, 5)=2.0 hours per day
That means he reads 2*50=<T>multiply(2, 50)=100 pages per day
So he reads 100*7=<T>multiply(100, 7)=700 pages in 7 days
