What is 10% of 450? A Simple Percentage Calculation
Finding 10% of a number is a fundamental percentage calculation. It's a skill useful in many everyday situations, from calculating discounts to understanding statistics. Let's break down how to find 10% of 450.
Understanding Percentages
A percentage represents a fraction of 100. 10% means 10 out of 100, or 10/100, which simplifies to 1/10. Therefore, finding 10% of a number is the same as finding one-tenth of that number.
Method 1: Using the Decimal Equivalent
The easiest way to calculate 10% of 450 is to convert the percentage to its decimal equivalent. 10% as a decimal is 0.10 (or simply 0.1). To find 10% of 450, we multiply 450 by 0.1:
450 * 0.1 = 45
Therefore, 10% of 450 is .
Method 2: Dividing by 10
