a)359, 56 m
b)78, 9 m
c)78, 8 m
Explicație pas cu pas:
a)
0, 21 km + 16 dam + 217 dm - 3214 cm =
210 m + 160 m + 21, 7 m - 32, 14 m =
370 m + 21, 7 m - 32, 14 m =
391, 7 m - 32, 14 = 359, 56 m
b)
0, 09 hm + 3240 cm + 5 dam - 125 dm =
9 m + 32, 4 m + 50 m - 12, 5 m =
41, 4 m + 50 m - 12, 5 m =
91, 4 m - 12, 5 m = 78, 9 m
c)
5300 cm + 240 dm - 5, 4 m + 0, 72 dam =
53 m + 24 m - 5, 4 m + 7, 2 m =
77 m - 5, 4 m + 7, 2 m =
71, 6 m + 7, 2 m = 78, 8 m
