How do you find X% / 20 percent of a number?

Step 1: Convert Percentage to Decimal: Divide the percentage value by 100 to convert it to a decimal.

Step 2: Multiply by the Number: Multiply the decimal value by the number you want to find the percentage of.

For example, to find X% of a number:

X% of a Number = (X / 100) × Number

Similarly, if you want to find 20% of a number, you would follow the same formula:

20% of a Number = (20 / 100) × Number = 0.20 × Number

Example 1: To find 30% of 200:
