No.

Yes...because a whole number does not have an irrational part to it.

No. More frequently it is not.

If the whole number is a perfect square, its square root is rational. If not, it's not.

When the whole number is a perfect square, ie it is a whole number squared.

No, it may be not even a rational number. Square root of 2 is 1,414213562... for example.

The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.

A perfect square is a rational number equal to the square of a whole number.

It is always rational.

A whole number is always rational.

A perfect square.

It is none of those because the square root of -9 is an imaginary number but the square root of 9 is 3 which is a rational integer or whole number

A rational number can always be written as (one whole number) divided by (another whole number). That's not only a characteristic of a rational number, it's the definition of one.

It can be written as a fraction, so it is rational. It is not an integer, whole number or irrational.

The √49 is 7. It is a rational number.

The square root of 4 is a whole number, an integer, rational and real.

It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational number.

Short answer - yes, fractions with whole numbers are rational. All whole numbers are rational. All fractions are rational. Rational numbers can be added to always make another rational number.

If the square root is a whole number, then the square of the square root, the original number, is also a whole number; all whole numbers can be expressed as themselves over 1, and so are rational numbers. The answer is thus any square number, ie the square of the natural numbers: 1 (1²), 4 (2²), 9 (3²), 16 (4²), etc.

Yes.

If the whole number is non-negative, then it can be a rational number or, more often, an irrational number.

A rational number is a number that can be expressed as the division of two integers, while the divisor is not zero. An irrational number is any number that is not rational.Whole numbers are rational, because the divisor is 1. It has nothing to do with square roots.

The square root of any positive integer can only be a WHOLE NUMBER or IRRATIONAL, so the square root of 7 is irrational.On the other hand, the sum of a rational and an irrational number is always irrational.

It is a real number, a rational number, an integer.

No, only a small minority are whole numbers.
