Let x   =    0.78367836...
thus 10,000 x =  7836.7836-     / you multiply both sides by 10,000 because                         -x   =         .7836           there are 4 repeating decimals
           9999 x  =   7836                    if there are one,multiply by 10 and so on
                    x   =   7836/9999
                actually in this particular case you don't have  to work out the problem . By inspection you will know the equivalent fraction is   7836/9999
