Answer 1

2) 60cm-6dm
430cm-43dm
530cm-53dm
1990cm-199dm
6m-60dm
7m+3dm=...dm
7m-70dm
70dm+3dm=73dm
9m+8dm=...dm
9m-90dm
90dm+8dm=98dm
6m+80cm=...dm
6m-60dm
80cm-8dm
60dm+8dm=68dm
3) 60dm-6m
500dm-50m
280dm-28m
960dm-96m
60km-60000m
75km-75000m
4km+6m=...m
4km-4000m
4000m+6m=4006m
9km+25m=...m
9km-9000m
9000m+25m=9025m
4) 500mm-5dm
7500dam-75km
3600dm-36dam
60hm-6km
6300cm-63m
90hm-9000m
