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.

## Step 1: Convert Numbers into Decimals

Since you want to figure out what percent 36 is to 45, start by turning that into a fraction:

**36/45**

... and then turning that fraction into a decimal:

36/45 = **0.8**.

## Step 2: Convert Decimal into Percent

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.
