a)
305 m - 17 000 mm + 4 dm = ?m
= 305 m - 17 m + 0,4 m =
= 288 m - 0,4 m=
= 287,6 m
dm < m de 10 ori
__________________________
b)
600 mm - 25 cm + 3 m = ? cm
= 60 cm - 25 cm + 300 cm =
= 35 cm + 300 cm =
= 335 cm
_________________________
c)
960 cm - 6 m + 58 dm - 1 200 mm = ? dm
= 96 dm - 60 dm + 58 dm - 12 dm =
= 36 dm + 58 dm - 12 dm =
= 94 dm - 12 dm =
= 82 dm
_______________________________
d)
800 m - 2 700 cm - 3 500 dm = ? m
= 800 m - 27 m - 350 m =
= 773 m - 350 m =
= 423 m
