    rational: - 3.786, 8/17, 8.23, 10.86731234, 0.75, √.49 = 0.7

    irrational: 3π, √11

    Step-by-step explanation:

    Any number that can only be represented completely using symbols, such as π or √, is an irrational number.

    If the number can be expressed as the ratio of two integers, it is a rational number. Such numbers include proper and improper fractions, integers, any number you can write with a finite number of digits, and any repeating decimal, regardless of the length of the repeat.
