1.99999999999999999999................................ഇത് ഭിന്നകമോ അഭിന്നകമോ ?


x = 1.999999999..........
10 x = 19.999999999999................

9 x = 18
x = 18/9 = 2, not equal to x but tends to x

  1. Good question!

    I feel it is irrational. As far I understand, an irrational cannot be written as p/q where q≠0 and p and q are integers. It appears this is not possible in the case... 2/1 is only ≃1.99999999....

    I may be wrong.... So, what is the answer?
