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
