## Is 13 a integer number?

For 13 to be an integer, 13 has to be a whole number. Furthermore, for 13 to be an integer, you should be able to write 13 without a fractional or decimal component. 13 is a whole number that can be written without a fractional component, thus 13 is an integer.

## Is 2/3 an irrational number?

For example 3=3/1, −17, and 2/3 are rational numbers. … Most real numbers (points on the number-line) are irrational (not rational). The rational numbers are those which have repeating decimal expansions (for example 1/11=0.09090909…, and 1=1.000000…

## Is 6 a rational number?

What about the number -6? -6 can be written as -6/1. Or 6/-1. Either way, -6 is a rational number, because it can be expressed as a fraction where the numerator and denominator are integers and the denominator doesn’t equal 0.

## Is 21 a real number?

Answer and Explanation: 21 is a whole number. Whole numbers include all positive integers.

## Is 25% an integer?

Integer Question: Is 25 an Integer? For 25 to be an integer, 25 has to be a whole number. Furthermore, for 25 to be an integer, you should be able to write 25 without a fractional or decimal component. 25 is a whole number that can be written without a fractional component, thus 25 is an integer.

## Why is Pi 22 divided 7?

But as you can see, 22/7 is not exactly right. In fact π is not equal to the ratio of any two numbers, which makes it an irrational number. A really good approximation, better than 1 part in 10 million, is: 355/113 = 3.1415929…

## Is 22 a irrational number?

Answer and Explanation: The square root of 22 is not a rational number. 22 is not a perfect square; there aren’t two integers that you can multiply together to get 22.
