The question goes like this: a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?

You read 30 pages of the book.

You have 90 pages left.

Step-by-step explanation:

120 total pages

⇒ 120 = 100%

pages have been read

⇒ = 25%

remaining

⇒ = 75%

120 x .25 = 30 pages read

120 x .75 = 90 pages unread

30 + 90 = 120

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
