Question

Sory read 45 percent of the pages in a book over 3 days, and he read the same number of pages each day. If the book is 600 pages long, how many more pages does sory need to read to finish the book

Answer 1

330 pages

Explanation:

Okay so let us look at what we actually need. It says that the book is 600 pages long and Sory read 45 percent over 3 days. This is actually all we need because it already tells us how much he read so far, which is 45%. If 45% is already done, how many percent is left?

100% - 45% = 55%

So he has 55% left of the book.

How many pages is that? We figure out how many pages is 55% of 600 pages. We just multiply 55% in fraction form by 600 pages.

`55\% = (55)/(100)\\\\ 600\:pages*(55)/(100)= 330\:pages`
