Understanding percentages is a fundamental part of everyday math. Whether you’re working on school assignments, managing budgets, or comparing values in a business report, knowing how to calculate “what percent X is of Y” can save time and reduce confusion.

How It Works

To calculate what percent X is of Y, the formula is:

Percentage = (X ÷ Y) × 100

For example, if X is 25 and Y is 200:

• Divide 25 by 200 = 0.125

• Multiply 0.125 by 100 = 12.5%

So, 25 is 12.5% of 200.
