64−−√
is a rational number.

π
is an irrational number.

0 is a natural number.

2/3
is a rational number.

Answer 1

Here are the answers for each statement:

1. -9 is a whole number. - False
   (Whole numbers are non-negative integers: 0, 1, 2, 3, ...)

2. √64 is a rational number. - True
   (√64 = 8, which is a rational number.)

3. π is an irrational number. - True
   (π cannot be expressed as a fraction of two integers.)

4. 0 is a natural number. - False
   (Natural numbers are typically defined as positive integers: 1, 2, 3, ...; but some definitions include 0.)

5. 2/3 is a rational number. - True
   (Any fraction where the numerator and the denominator are integers and the denominator is not zero is rational.)

So the final answers are:

1. False
2. True
3. True
4. False
5. True
