How do you find 15% of a number?

To find 15% of a number, multiply the number by 0.15.

Finding 15% of a number involves understanding percentages and basic multiplication. A percentage represents a fraction of 100, so 15% means 15 out of every 100. To convert a percentage to a decimal, you divide by 100. For 15%, this means 15 ÷ 100 = 0.15.

Once you have the decimal form, you simply multiply it by the number you are interested in. For example, if you want to find 15% of 200, you would calculate 200 × 0.15. This equals 30, so 15% of 200 is 30.

Another way to think about it is to break it down into smaller, more manageable steps. First, find 10% of the number by dividing it by 10. For instance, 10% of 200 is 20. Then, find 5% by halving the 10% value. In this case, 5% of 200 is 10. Finally, add these two results together: 20 (10%) + 10 (5%) = 30. This confirms that 15% of 200 is indeed 30.

This method can be applied to any number, making it a versatile and useful skill in various real-life situations, such as calculating discounts, interest rates, or proportions in recipes.
