0.7......    

 

First....find the fractional representation of this.....

 

Take  the  repeating part = 7   

This is the  numerator of our fraction

 

For the denominator,  write the  number of  9's   equal to  the number of digits in the  repeating part =  one  9

 

So....  0.7.......  =   7/9

 

The reciprocal  = 9/7
