109% 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. It has a value that can be converted into a decimal. A decimal is a way to represent a number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

What is 109% as a decimal?

109 percent as a decimal

 

 

Answer

109% as a decimal can be written as 1.09.

 

Explanation

To convert 109% to a decimal, we divide by 100. The percentage sign (%) means "per hundred," so to remove the percentage and convert to a decimal, we shift the decimal point two places to the left.

 

Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the percentage value, which is 109%.

 

Step 2: To convert it to a decimal, divide 109 by 100.

 

Step 3: 109 ÷ 100 = 1.09.

 

Thus, 109% as a decimal is 1.09.
