The number 1.256 is A)rational number.
Step-by-step explanation:

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