If you can find any common factor of the numerator and denominator, divide each of them by it. 32 and 45 have no common factor (except ' 1 '), so 32/45 is the simplest form. 64 and 90 have the common factor of 2. So if you see 64/90, divide the top and bottom both by 2, and you get 32/45, which is the simplest form.
