- Sir 22/7 is pie .....and pie is irrational , then why is 22/7 rational.(1 vote)
- 22/7 is a rational number as both the numerator and denominator are integers.
Now, pi is irrational because it is non-terminating and non-recurring. 22/7 is an estimated value of pi, it is not the real value. The real value of pi is 3.141592653589793238.....
It never ends.

- sir non terminating and repating is irrational or rational(1 vote)
- Good question. It is Rational because it is repeating. If a number is non-terminating and non repeating then it is Irrational. For example 0.33333...is non terminating but is repeating so we can represent it as 1/3 which is a rational number but lets take a pie it's value is 3.141592653589793238..... and it is non-terminating and non-repeating number so we can't represent it in the form of Rational number. So ultimately pie is not a rational number. Hope this helps :)(1 vote)
- and terminating and repeating is rational or irrational.I am just confuse in this concept.(1 vote)
- Hi Arpit. Terminating means the numbers after decimal should end at some point. Like 1.618, the number is ending at digit 8. Repeating means the number after the decimal should never end and the digits should repeat. Like 0.33333333..., the number never ends but the digit 3 is repeating. Either terminating or repeating is possible but both terminating and repeating is not possible. On the other hand, It can be non-terminating + repeating or terminating + non-repeating but terminating + repeating is not possible. Hope this helps :)(1 vote)
