100 as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on decimal representation. Understanding decimals is crucial here. A whole number like 100 is a number that has no fractional part. Decimals are used to represent numbers that are not whole, using a decimal point (.) to separate the whole part from the fractional part. In the case of whole numbers, there is no need for a fractional part, but they can be expressed in decimal form as well.
