400% 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 is a way to express a number as a fraction of 100. 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.

400 percent as a decimalAnswer

 

400% in decimals can be written as 4. It is a whole number because 400% represents 400 out of 100, which is equivalent to 4.

 

Explanation

 

To convert 400% into a decimal, we will use the following method:

 

Step 1: Understand that "percent" means "per 100." Therefore, 400% means 400 per 100.

 

Step 2: To convert a percentage to a decimal, divide the percentage by 100.

 

Step 3: Divide 400 by 100, which equals 4.

 

Hence, 400% as a decimal is 4.
