 0.3939   this is a rational number because it can be expressed as the ratio  3939 / 10000

 

√ 45  =   3√5        any  number that has a square root remaining after we simplify it is irrational

 

9      is  rational [ can be expressed as a ratio such as 18/2, etc.]......also an integer    ....also a whole number [ a "counting number" or  0]

 

-2  is rational  [ can be expressed as the ratio such as   -4/2 , etc] ......also an integer ...it is not a whole number because it is not a "counting" number or 0
