31 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to understand whole numbers and decimals. A whole number is a non-fractional number that is complete by itself. In our case, 31 is already a whole number. A decimal is a way to represent numbers, especially those involving fractional components, using a decimal point (.) to separate the whole part from any fraction part. The numbers to the left of the decimal point represent the whole, while those to the right represent the fractional part.
