Answer:
Explanation:
3/4=75%
75%x64=48 math books
math books divided by total # of books = percent of math books
(Substitute that^) 48 divided by 64 = 0.75 = 75%.
A quicker way to solve this if you don't need to show work is to see that 3/4 = 75% and since 3/4 of the books are math, you can substitute 3/4 for 75% and now you know 75% of the books are math books. Hope this helps!
