WebA number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. WebA few examples of irrational numbers are π, 2, and 3. (In fact, the square root of any prime number is irrational. Many other square roots are irrational as well.) The values of π, 2, and 3 are shown below to 50 decimal places. (Notice the nonrepeating nature of the numbers.)

WebA real number that can NOT be made by dividing two integers (an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number. We aren't saying it's crazy! Its decimal also goes on forever without repeating. Example: π (the famous number "pi") is an irrational number, as it can not be made by dividing two integers. WebSo, if a² = 7.29. Then, a = 7.29. = 7.29 100. = 27 10. a = 27 10, from the definition of irrational numbers we know that, a number is irrational if it cannot be written in the form of p q, where p and q are integers. Here 27 10 is of the form p q where both 27 and 10 are integers. Hence, 27 10 is a rational number.
