Theresa and Isaiah are comparing the number of pages that they read for Summer Reading. Theresa read 2,205 pages, which was 75% of the number of pages that Isaiah read. How many pages did Isaiah read?

Respuesta :

100-75= 25 so 25% is what Isaiah read then u find 2,205 of 25%
(OF means multiply easier way 2,205*0.25= 551.25 but rounded it would be 552 so Isaiah read 552 pages
Set up a problem: 2205=.75p.
Divide to get the unknown by itself: 2205/.75=2940.
P=2949 :)
