You need to divide 21/4 by 3/1, not multiply it. 21/4*1/3 would you give you a per hour rate of 21/12. multiply that by 8 and you get 14.

jaspreets -
21/4 is actually 5 and 1/4. If Henry can write 5.25 pages in 3 hours. that would be 1.75 pages per hour.
Your set up is incorrect because 21/4 divided by 3 would actually be 21/4 x 1/3 or 21/12 which is 1.75 as above.
