Question

Write four irrational numbers between 0.1 and 0.2.

Answer 1

Non-repeating and non-terminating decimals are irrational numbers; thus, any such numbers lying between 0.1 and 0.2 will be irrational.
These can be 0.125986634275... ,0.165323296581422..., 0.121221222212226... and 0.13133133331333311333...
