-1 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal representation. Firstly, we need to understand integers and decimals. An integer is a whole number that can be positive, negative, or zero. Here, -1 is an integer, representing a value one less than zero. 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. In the case of integers, if there is no fractional part, the number can still be written with a decimal point followed by zero to indicate the absence of a fractional part.

What is -1 as a decimal?

 

-1 as a decimal

Answer

 

-1 in decimals can be written as -1.0. This indicates that -1 is a whole number, and there is no fractional part.

 

Explanation

 

To express -1 as a decimal, we acknowledge that it is already a whole number. While the decimal form typically represents numbers with fractional components, any integer can be expressed with a decimal point followed by zero to clarify the absence of a fractional part. Therefore, -1 can be written as -1.0. This format is useful for calculations that involve both integers and decimals, maintaining consistency in representation.
