Identify all the sets to which the number belongs. choose from rational number, irrational number, whole number, integer.
1.256
rational number
irrational number
integer, rational number
whole number, integer, rational number

The given number is (A) rational number.

Step-by-step explanation: We are given to choose all the sets from the given options to which the number 1.256 belong.

We have the following sets:

The set of integers is {. . . , -2, -1, 0, 1, 2, . . .}. They are no non-zero digits after the decimal.

The set of whole numbers is {0, 1, 2, 3, . . .}. Here also, there are no non-zero digits after the decimal.

A rational number is one in which the digits after the decimal are either terminating or repeating. Also, they can be writte in the form

For example, , 1.25, 1.333 . . ., etc.

An irrational numbers is one in which is not rational, or the digits after the decimal are non-repeating and non-terminating. For example, √3, 1.36366353 . . ., etc.

Given number is 1.256. Since the digits after the decimal are terminating, and also it can be written as

So, 1.256 is a rational number.

Thus, the correct option is (A) rational number.
