Which one of the following is not true?

As we know an irrational number are those number which cannot be represented in a simple fraction

A. √2 cannot be represent in simple fraction hence it is an irrational number

Hence A is true

B. √17 cannot be represent in simple fraction hence it is an irrational number

Hence B is true

C. 0.10110011100011110….cannot be represent in simple fraction hence it is a irrational number . Hence C is true

D. on simplification

=

Hence is rational number and not irrational.

Hence D is the right answer
