Is 23 a rational number?

Answer 1

Yes. #23 = 23/1 = 46/2 = 69/3#
A rational number can be written as a fraction.

A Rational number is a Real number which can be written as a fraction with the numerator and denominator both being integers. (whole numbers) #a/b, b != 0# (The denominator may not be 0)

All common fractions, all terminating decimals (such as 3.875), all recurring decimals (such as 4.121212....), all integers (....-3, -2, -1, 0, 1, 2, 3....), all counting (whole) numbers (0, 1, 2, 3....), and all natural numbers (1, primes and composites) (1, 2, 3, 4,.....) are examples of rational numbers.

-The irrational numbers are the following real numbers:

Square roots of numbers which are not perfect squares #sqrt20# Cube roots of numbers which are not perfect cubes #root(3)12#

Yes, 23 is a rational number because it can be expressed as the quotient of two integers, where the denominator is not zero. In this case, 23 can be expressed as ( \frac{23}{1} ), where both 23 and 1 are integers. Therefore, 23 meets the criteria to be classified as a rational number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
