20 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal representation. Numbers can be represented in different forms, including whole numbers and decimals. A whole number is an integer without a fractional or decimal part. A decimal is a way to express numbers using a decimal point to separate the whole part from any fractional part. The numbers to the left of the decimal point represent the whole number, and those to the right represent the fractional part, if any.

20 as a decimal

 

Answer

 

20 as a decimal is written as 20.0. It is a terminating decimal because it does not have any infinite repeating digits.

 

Explanation

 

To represent the whole number 20 as a decimal, we simply add a decimal point followed by a zero. This does not change the value of the number, but it shows that there is no fractional part.

 

Step 1: Identify the whole number, which is 20 in this case.

 

Step 2: Add a decimal point followed by a zero to indicate the absence of a fractional part. The process is straightforward as the number is already an integer, so adding ".0" confirms its representation as a decimal.

Therefore, the decimal representation of 20 is 20.0.
