Explicație pas cu pas:
a
123 mm=1.23 dm
17.15 cm=1.715 dm
2 m=20 dm
1.23+1.715+20=22.955 dm
b
15.99 km=1599 dam
18 hm= 180 dam
2358 m= 235.8 dam
1599+189+235.8=2023.8 dam
c
93 m=93000 mm
88.38 dam= 883800 mm
1000 cm= 10000 mm
93000+883800+10000=986800 mm
d
861 mm= 86.1 cm
13 dam= 13000 cm
17.232=1723200000 cm
86.1+13000+1723200000=1723213086.1 cm
e
15.17 mm= 0.01517 m
11.324 cm=0.11324 m
0.17 dm=0.017 m
0.01517+0.11324+0.017=0.14541
f
2.7 hm=0.27 km
130 dam=1.3 km
1+0.27+1.3=2.57 km
