-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.

What is -8 as a decimal?

-8 as a decimal

Answer

 

-8 in decimals can be written as -8.0. Since -8 is already a whole number, its decimal representation simply adds a ".0" to indicate there is no fractional part.

 

Explanation

 

To express -8 as a decimal, we consider that any whole number can be represented with a decimal point followed by zero. This is because the decimal point separates the whole number from the fractional part, which in this case is zero.

 

Step 1: Identify -8 as the integer we want to convert to a decimal.

 

Step 2: Recognize that -8 is already a whole number, so we write it as -8.0.

 

Step 3: The ".0" indicates there is no fractional part to the number.

 

Therefore, the decimal representation of -8 is -8.0.
