Math and Arithmetic

That can refer either to integers, or only to non-negative integers - basically, the counting numbers. (Integers includes negative numbers.) Since "whole numbers" has this ambiguity, it's best to avoid this term. The following is the answer.

The whole numbers are all numbers zero and up (including zero ).

no

Yes.

no . but all natural numbers are whole numbers

None. Perfect squares, by definition, are the squares of counting numbers and these cannot be fractions.

It is a rational number but not an integer.

Yes.

4=4/1

25=25/1

9.4

All natural numbers are rational numbers.

No irrational numbers are natural numbers.

1 is a rational number, as you can express it as a fraction: 1/1 = 2/2 = 3/3 = 4/4 ... n/n = 1 for finite n.

It's 3, what's to evaluate?

No. Rational numbers are numbers that can be written as a fraction. All rationals are real, but not all real are rational.

To the nearest 100, it is 0.

To the nearest 100, it is 0.

To the nearest 100, it is 0.

To the nearest 100, it is 0.

By definition, ALL perfect squares are whole numbers!

No.

83.25 rounded to the nearest whole number is 83

512.715 rounded to the nearest whole number would be 513.000.

Yes, 0.25 is a rational number because it can be expressed as a fraction in the form of 1/4

An absolute value must be greater or equal to zero. If the absolute value is known to be nonzero then it must be greater than zero: that is, it must be positive. The product of two (or more) positive numbers must be positive.

It is already rounded to the nearest integer.
