How do you find out what percent one number is of another?

To find out what percent one number is of another, you can use the following formula:

Step 1: Divide the first number by the second number.
Step 2: Multiply the result by 100.

Let's clarify with an example. Suppose you want to find out what percent 25 is of 100.

Step 1: Divide 25 by 100:
25 ÷ 100 = 0.25

Step 2: Multiply the result by 100:
0.25 × 100 = 25%

Therefore, 25 is 25% of 100.
