-8 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to understand integers and decimals. An integer can be positive or negative, representing a whole number. Decimals are a way to represent numbers that are not whole, using a (.) or a decimal point to separate the whole part from the fractional part. Here, -8 is an integer, which means it is already a whole number and can be represented directly in decimal form without any fractional part.
