f 5900 cm - 14 m - 3000 mm= ......... m;​

Answer 1

a) 2.13 cm + 5.6 cm + 123 cm= .130,73cm;

c) 1,2 km - 2,8 dam = 120000-2800=117200cm;

e) 43000 mm - 210 dm = .43-21=22m;

g) 4. 109 cm - 18 hm = 0,4109-1,8=-1,3891km.

b) 10.153 dm + 1 400 000 mm: 100 = 1015,3+1400=2414,3 m;

d) 5000 mm +1200 cm - 70 dm = 5+12-7=10m;

f) 5900 cm - 14 m - 3000 mm= 59-14-3=42 m;
