-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.

• Integer: A whole number that can be positive, negative, or zero, without any fractional part.

• Decimal: A number expressed using the base ten system, which can include a decimal point to separate the whole part from the fractional part.

• Negative Number: A number less than zero, represented with a minus sign (-).

• Whole Number: A non-fractional number, which can be positive, negative, or zero.

• Decimal Point: A dot used to separate the whole part of a number from its fractional part in decimal notation.
