30 as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question on decimal conversion. Firstly, we need to understand whole numbers and decimals. A whole number is a complete unit without any fractional part, while a decimal is a way to represent numbers that are not whole, using a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole part, and those to the right represent the fractional part.
