Question

type 1 over 3, of a page in 1 over 5, of an hour. At this rate, how many pages will he type in one hour? Express the answer as a decimal rounded to the nearest hundredth.

Answer 1

1/3 of a page in 1/5 hr or 60/5 min = 12 min

 

so 12 min for 1/3 of a page

 

     1 min  for (1/3)(1/12) page

in 60 min  it will be (1/3)(1/12) (60) pages = 5/3 or 5 over 3 page

= 1.66 page (which means one plus 2 over 3 of a page)

 

 

 

Answer 2

p represents the number of pages

1/3 : 1/5 :: p : 1       proportion

(1/5)p = 1/3             product means/extremes

p = 5/3
