is sqrt 2 a whole number integer rational or irrational select all that apply
Understand what 'rational' and 'irrational' actually mean and you will find these questions easy.
A rational number is just a number that can be expressed as a ratio (like a fraction) of two whole numbers. For example 0.3 is rational because you can write it as the ratio of the two whole numbers 3 and 10 to get 0.3 = 3/10.
An irrational number is one that CAN't be expressed as a ratio of two whole numbers. An obvious one is pi, so is sqrt(2).
