20 as a Decimal

Answer

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.
