2.5 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we need to understand the concept of decimals. A decimal is a way to express numbers that are not whole, using a decimal point to separate the whole part from the fractional part. For example, the number 2.5 has a whole part (2) and a fractional part (5/10 or 0.5). The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
