First, recognize that, one way to convert a fraction into a percent is to multiply the numerator by 100 and evaluate the new fraction.
For example, 1/4 = (100)(1)/4 percent = 100/4 percent = 25 percent
Likewise, 6/5 = (100)(6)/5 percent = 600/5 percent = 120 percent
Second, we need to recognize that there's a nice fraction hiding in 62.5
If we recognize that 0.625 = 5/8 [a useful conversion to know], then 62.5 = 500/8
So we have,
5/62.5 = (100)(5)/62.5 percent
= (100)(5)/(500/8) percent
= 500/(500/8) percent
= (500)(8/500) percent
= 8 percent
