D. Whole number, Integer, and rational number

Answer 1

The number 1.256 is A)rational number.

Explanation:

• A whole number is a non-negative number without any digits behind the decimal.

• An integer is a set of negative and non negative numbers that don't have any digits behind the decimal.

• A number that can be shown as a fraction of two whole numbers is a rational number.And the numbers that are not rational are irrational numbers.

• Here, 1.256 is a fraction of whole numbers 1256 and 1000 , so it is a rational no.

`(1256)/(1000) =1.256`

• But since it has digits behind the decimal it is neither a whole number, or an integer.
