As we know that : 1 m = 100 cm

Answer 2

Here given to fing diff between 3m5cm and 350cm

(1 m = 100cm )

I.E 3m=3*100cm

         =300cm

so 3m 5 cm =300cm+5cm

                    =305cm

Now diff between 350cm and 305 cm is =350-305cm

                                                                   =45cm
