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.
