Whether you're shopping for deals, need help with a little math, or any number of other occasions, it's a valuable skill to know how to quickly figure out a percentage given two numbers.
Let's say you're shopping and you come across a pair of shoes that are normally $45, but now they're on sale for $36. To figure out just how much of the original price you're paying, you just need some quick math.
Since you want to figure out what percent 36 is to 45, start by turning that into a fraction:
... and then turning that fraction into a decimal:
36/45 = 0.8.
Now that you have the decimal, simply multiple it by 100 to get the percentage:
0.8 X 100 = 80
... which leaves us with 80%!
So, to sum up, 36 is 80% of 45, which means that pair of shoes is only going to cost you 80% of what they normally cost.
