Understanding decimal representation is straightforward. A decimal represents a number using a base ten system, which includes a decimal point to distinguish the whole part from the fractional part. In this context, though, we are discussing whole numbers like 400, which can be directly represented as a decimal without any fractional component. The decimal point is followed by zero, indicating there is no fractional part.
400 as a decimal is written as 400.0. It is a terminating decimal, meaning it does not repeat infinitely.
To express 400 as a decimal, we simply place a decimal point followed by a zero, indicating that there are no fractional parts:
Step 1: Identify the whole number, which is 400.
Step 2: As there are no fractional components, append ".0" to the whole number.
Step 3: The result is 400.0, a terminating decimal.
