Question

a) 0,21 km + 16 dam +217 dm - 3214 cm;
b) 0,09 hm + 3240 cm + 5 dam - 125 dm;
c) 5300 cm + 240 dm - 5,4 m +0,72 dam.

Answer 1

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
