A) 305 m - 17000mm+ 430dm=?m
17000/1000=17→17000mm=17m
430/10=43→430dm=43m
305m-17m+43m=331m

B)600mm-25cm+3m=?cm
600/10=60→600mm=60cm
3/100=0.03→3m=0.03cm
60cm-25cm+0.03cm=35.03cm

C)960cm-6m+58dm-1200mm=?dm
960/10=96→960cm=96dm
6/100=0.06→6m=0.06dm
1200/100=12→1200mm=12dm
96dm-0.06dm+58dm-12dm=141.94dm

D)800m-2700cm-3500dm+7000mm=?m
2700/100=27→2700cm=27m
3500/10=350→3500dm=350m
7000/1000=7→7000mm=7m
800m-27m+350m+7m=430m
