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

330 pages

Step-by-step 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.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
