5 1/4 = 21/4 = 5.25

5.25 pages in 3 hours

5.25 / 3 = 1.75 pages per hour

in 8 hours = 8 x 1.75 = 14 pages

He read 5 1/4 pages in 3 hours.

Divide 8 hours by 3 hours to see how many 3 hour segments there are:


8/3 = 2 2/3


Now multiply 5 1/4 by 2 2/3 for total pages:


Convert to improper fractions first:


5 1/4 = 21/4

2 2/3 = 8/3


So you have 21/4 x 8/3


Cancel out the common factor of 3


7/4 x 8/1


Cancel out the common factor of 4:


7/1 x 2/1


Now multiply straight across:


7 x 2 / 1 x 1 = 14/1 = 14 pages total.
