What is the easiest / fastest way to figure out 5/62.5? Thanks!

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 = 500/8So 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

Cheers,

Brent
