15% as a decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to understand percentages and decimals. A percentage represents a part out of 100. The number before the percent sign indicates how many parts out of 100. A decimal is a way to represent a number that is not whole, using a (.) or a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, while those to the right represent the fractional part.

What is 15% as a decimal?

15 percent as a decimal

 

Answer

 

15% in decimals can be written as 0.15. It is a terminating decimal, meaning it does not repeat infinitely.

 

Explanation

 

To convert 15% to a decimal, we divide the percentage by 100. This is because "percent" means "per hundred." Let's see the step-by-step breakdown of the process:

 

Step 1: Take the percentage number, which is 15.

 

Step 2: Divide 15 by 100 to convert it to a decimal: 15 ÷ 100 = 0.15.

 

Step 3: The result, 0.15, is the decimal representation of 15%. This process is straightforward since the decimal stops after two places.
