Question

Calculează.
a. 12 dam + 2 km = ? m
8 km + 15 dam = ? m
52 km - 98 dam = ? m
b. 8 m + 125 dm = ? cm
70 dm + 18 cm = ? mm
3 000 cm + 180 dm = ?m
c. 85 dam - 13 m=? am
5 km - 82 m = ? am
84 km - 15 dam = ? m​

Answer 1

Răspuns:

a. 12 dam + 2 km = 120 m+2000m=2120m

8 km + 15 dam =8000 m+150m=8150m

52 km - 98 dam = 5200 m-980m=4 220m

b. 8 m + 125 dm =800 cm+1250cm=2050cm

70 dm + 18 cm = 7000 mm+180mm=7180mm

3 000 cm + 180 dm = 30m+18m=48m

c. 85 dam - 13 m=850m-13m=837m

5 km - 82 m = 5000m-82m=4918m

84 km - 15 dam = 84000m​-150m=83850m
