Answer:
You read 30 pages of the book.
You have 90 pages left.
Step-by-step explanation:
120 total pages
⇒ 120 = 100%
[tex]\frac{1}{4}[/tex] pages have been read
⇒ [tex]\frac{1}{4}[/tex] = 25%
[tex]\frac{3}{4}[/tex] remaining
⇒ [tex]\frac{3}{4}[/tex] = 75%
120 x .25 = 30 pages read
120 x .75 = 90 pages unread
30 + 90 = 120
