All whole numbers ( also negative integers like -30) are rational because they can be converted to a fraction ( like -30/1).
Numbers with a finite number of decimals ( like 58.25 and -8.3 ) are also rational as they can e converted to a fraction (58 .25 = 58 1/4 or 233/4)
Numbers with repeating decimals ( for example 17.3333333..) are also rational - this number can be written as 17 1/3 or 52/3.
π is irrational as it cant be written as a fraction The decimal form continues without bounds.
