Hi,

Erika read 90 pages in 2 1/2 hours. At the same time, 

how many hours would it take her to read 225 pages?

 Let n represent the number of  hours would it take her to read 225 pages 

Set up the Proportion:

90%2F2.5hrs+=+225%2Fn

90n = (2.5)(225)   

 n =  %28%282.5%29%28225%29%29%2F90

n = 6.25hr   0r 6 1/4 hr

Wish You the Best in your Studies.
