960cm-6m+58dm-1200mm=?dm
800m-2700cm-3500dm+7000mm=?m

Answer 1

960cm= 96dm - 60dm +58dm-12dm=36dm+46dm=82 800m-27m-350m+7m=773-350+7=423+7=430

Answer 2

960 cm - 6 m + 58 dm - 1 200 mm=? dm

960 cm = 96 dm
6 m = 60 dm
58 dm = 58 dm
1 200 mm = 12 dm

96 dm - 60 dm + 58 dm - 12 dm =
36 dm + 58 dm - 12 dm =
94 dm - 12 dm =
82 dm



800 m - 2700 cm - 3500 dm + 7000 mm=? m

800 m = 800 m
2 700 cm = 27 m
3 500 dm = 350 m
7 000 mm = 7 m

800 m - 27 m - 350 m + 7 m =
773 m - 350 m + 7 m =
423 m + 7 m =
430 m
