Identify all the sets to which the number belongs. Choose from Rational Number, Irrational number, whole number, and integer. 1.
Allushta [10]

Answer:

The number 1.256 is  A)rational number.

Step-by-step 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.

                     \frac{1256}{1000} =1.256

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