Exercise 1.3 - Question no. 6

in this question, we have to find three irrational numbers. So,

5/7= 0.714285 where 714285 are repeating.

9/11=  0.81 where 81 are repeating.

so the three irrational numbers should be greater than 0.714285... and smaller than 0.8181...

now the irrational numbers will be= 0.207200720007... 

                                                        0.7307300730007... and 0.740740074007...
