Repeated - .3535353535353535.......... or .35 with a bar on top

Rounded to hundredths - 0.35

Rounded to tenths - 0.4

Without rounding:

Let             x  =  0.3535353535...

Then   100x  =  35.35353535...

 

Writing these in reverse order:  100x  =  35.3535353535...

                                                            x  =     0.3535353535...

Subtracting:                                    99x  =  35

Divide by 99:                                       x  =  35/99
