Answer 1

a) 305 m - 17000 mm + 430 dm = 331 m

17000 mm = 17 m
430 dm = 43 m

305 m - 17 m + 43 m = 331 m
288 m + 43 = 331 m

b) 600 mm - 25 cm + 3 m = 38 cm

600 mm = 60 cm
3 m = 300 cm

60 cm - 25 cm + 3 m = 38 cm
35 cm + 3 cm = 38 cm
 
c) 960 cm - 6 m + 58 dm - 1200 mm = 82 dm

960 cm =96 dm
6 m =60 dm
1200 mm =12 dm

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

d) 800 m - 2700 cm - 3500 dm + 7000 mm = 403 m

2700 cm = 27 m
3500 dm = 350 m
7000 mm = 7 m

800 m - 27 m - 350 m + 7 m = 403 m
773 m - 27 m - 350 m + 7 m = 403 m
746 m - 350 m + 7 m = 403 m
396 m + 7 m = 403 m
