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.
