Answer:
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.
[tex]55\% = \dfrac{55}{100}\\\\ 600\:pages\times\dfrac{55}{100}= 330\:pages[/tex]
