# Another name for a whole number and fraction or decimal are?

Whole numbers include natural numbers (that begin from 1 onwards), along with 0. A decimal number system is used to express the whole number and fraction together.

## Answer: Another name for whole numbers is positive integers including 0 and fractions or decimals can be called rational numbers.

Let's see in detail.

**Explanation:**

An Integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero. Examples of integers are: - 2, -1, 0, 1, 2 and 101.

A set of integers, which is represented as Z, includes:

**Positive Integers**: An integer is positive if it is greater than zero. Example: 1, 2, 3 . . .

**Negative Integers**: An integer is negative if it is less than zero. Example: -1, -2, -3 . . .

**Zero** is defined as neither negative nor positive integer.

**Z** = {… -5, -4, -3, -2, -1, 0, 1, 2, 3, …}

Hence, we can say that whole numbers are positive integers including 0.

Every decimal number (except non-terminating non-repeating) can be expressed in the form of a fraction.

For example, 1.25 can be expressed into fraction as 125/100 or 5/4.

If a number can be expressed as a fraction where both the numerator and the denominator are integers, the number is a rational number.

For example, 1/2, 3/2, 2.5, 1.25, etc.

Hence, we can say that fractions or decimals are rational numbers.

### Thus, whole numbers are positive integers including 0, and fractions or decimals are rational numbers.
