Question

So I'm a bit rusty at this stuff but which set of numbers(real,rational,integer,whole,natural,irrational) do -2/9, -square root 10, -31, and square root 121. ty

Answer 1

Real: It's not imaginary/complex!
Rational: It can be expressed as a fraction, repeating decimal (i.e. .3333333 forever), or a decimal that ends
Integer: Positive or negative whole numbers and 0 (-2, -1, 0, 1, 2)
Whole: Positive integers and 0 (0, 1, 2, 3)
Natural: Positive integers (1, 2, 3, 4, NOT 0)
Irrational: CAN NOT be expressed as a fraction, repeating or terminating decimal (pi, sqrt(2) etc.)

Answer 2

so \[\sqrt{121}\] would basically be everything but irrational right?

Answer 3

Yup

Answer 4

alright

Answer 5

kind of have a basic idea ty
