Here's how, using #8 as an example
5/8 = x/100
(always use x/100 because percent means divided by 100)
cross multiply 8x = 500
divide 500 by 8 which is 62.5So it is 62.5 %

3/4 = .75 x 100% = 75%
7/10 = .7 x 100% = 70%
1/20 = .05 x 100% = 5%
3/25 = .12 x 100% = 12%
29/50 = .58 x 100% = 58%
1/8 = .125 x 100% = 12.5%
5/8 = .125 (from above) x 5 = .62 5= 62.5% or
5/8=.625 x 100% = 62.5%

divide (i.e. 3/4=?)
move the decimal to the left two spaces. It is now a percent!
