Question

how to find rational and irrational​

Answer 1

Answer:

rational no can be expressed in p/q form where denominatior q is not equal to 0 but irrational numbers can't be expressed in p/ q form

so buy converting them into fraction you can distinguish between them

Answer 2

Answer:

The numbers having decimal expansion terminating and non terminating recurring then it is a rational no.

If the decimal expansion is non terminating non recurring then it is a irrational no.

If you want to find two irrational or rational no. between any no.

Then follow the steps.

1. Take two numbers. ex - 1 and 2
2. two irrational nos. between 1 and 2. Write any number between 1 and 2 then the decimal expansion must be non terminating non recurring. ex - 1.01001000100001....
3. Here in this example no numbers are repeating and non terminating.
4. Similarly with irrational nos.
5. take no. between 1 and 2
6. Make it decimal expansion terminating or non terminating but recurring
7. ex- 1.2 or 1.333333333....
8. both are rational nos.
