Question

Mike write 5 1/2 pages of a report in 2 1/3 hours. What is the average number of pages you write per hour?

5 1/2 divide by 2 1/3?
11/2 divide by 7/2
11/2 X 2/7 = 22/14 = 1 8/14??

Answer 1

Correct Answer:

5 1/2 divide by 2 1/3
11/2 divide by 7/3

11/2 X 3/7

33/14

= 2 5/14 pages (correct answer)

Answer 2

5 1/2 = 5 + 1 / 2 = 10 / 2 + 1 / 2 = 11 / 2

2 1/3 = 2 + 1 / 3 = 6 / 3 + 1 / 3 = 7 / 3


5 1/2 /2 1/3 = ( 11 / 2 ) / ( 7 / 3 ) =

11 * 3 / 2 * 7 = 33 / 14


33 / 14 = 28 / 14 + 5 / 14 = 2 + 5 / 14 = 2 5/14


Average number of pages = 33 / 14 = 2 5/14
