Answer:
Rafael will read 240 pages.
Step-by-step explanation:
Let's start by setting up the unknowns:
x = # of Rafael's pages
x/2 = # of Philippe's pages
(3/4)x = # of Denise's pages
Set these all equal to 540:
(x) + (x / 2) + (3/4(x)) = 540
Let's multiply both sides by 4 to make this easier.
4x + 2x + 3x = 2160
9x = 2160
x = 240
x was the # of Rafael's pages, so Rafael will read 240 pages. This means that Philippe will read 120 pages (one-half of Rafael), and Denise will read 180 pages (three-fourths of Rafael). Adding these all up will get you 540 pages, so it checks out.
Hope this helps!
