I assume we have  3.424242......

 

Take the repeating and non-repeating part [ without the decimal ] and subtract the non-repeating part

[ 342  - 3 ]   =  339    (1)

 

Write  an integer with the same number of "9s"  as the number of repeating digits   = 99     (2)

 

Put    (1)  over (2)  =

 

339  / 99

 

Check to see that     339 / 99  =   3.424242......
