Question

What are decimal numbers ?

Answer 1

Define decimal numbers.

A decimal number is one in which the whole number and fractional parts are separated by a decimal point. In a decimal number, a decimal point is a dot. A value less than one is represented by the digits after the decimal point. Decimals are numbers that fall between integers on a number line. They're just another way of writing fractions. Decimals can be used to write more precise quantities for items such as length, weight, distance, and money.

Consider an example.

$13.27$ is a decimal number.

Here,

$13$ is a whole number part.

$27$ is a decimal part or fractional part and represents the fractional part.

$\left(.\right)$ is a decimal point.

Therefore, the numbers that express both whole numbers and fractions are decimal numbers.
