A galvanometer has a coil resistance of 34.0 . It is to be made into a voltmeter

Question:

A galvanometer has a coil resistance of 34.0 Ω. It is to be made into a voltmeter with a full-scale deflection equal to 100.0 V. If the galvanometer deflects full scale for a current of 0.120 mA, what size resistor should be placed in series with the galvanometer?
