How to Find the Percent of a Number
Finding the percent of a number is a common math task. Here’s a simple step- by-step guide:
Step 1: Understand What Percent Means
- Percent means "per hundred."
- For example, 25% means 25 out of 100.
Step 2: Convert the Percent to a Decimal
- To convert a percent to a decimal, divide by 100.
- Example: 25% ÷ 100 = 0.25
Step 3: Multiply the Decimal by the Number
- Multiply the decimal form of the percent by the number you want to find the percent of.
- Example: To find 25% of 80, calculate 0.25 × 80 = 20
Formula
Percent of a number=(Percent100)×Number\text{Percent of a number}=\left(\frac{\text{Percent}}{100}\right)\times \text{Number}Percent of a number=(100Percent)×Number
Example
Find 15% of 200:
- Convert 15% to decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 200 = 30
- So, 15% of 200 is 30.
