The decimal number is a way to represent a simple fraction or a number that is not whole.

The decimal point (or decimal comma in some areas) divides the number in the following way:

For example, when checking a fever, on the thermometer there is a number like $37.5$ or $36.4$.

The point that separates the figures is the decimal point, therefore, the number in question is a decimal number.

When we weigh ourselves, we step on the scale and, also in this case, the very same decimal number appears!

The weight is shown with the decimal point and expresses, in a clear and simple way, a number that is not whole.
