# Find the smallest positive rational number by which 1/7 should be multiplied so that its decimal expansion terminates after 2 places of decimal.

And here we have $\frac{1}{7}$  , So  our numerator must be 7 , so we can cancel out 7 from denominator to get terminating decimal digits  ,
Our smallest rational number by which $\frac{1}{7}$  should be multiplied so that its decimal expansion terminates after 2 places of decimal.  =                                                           (  Ans  )
