500m+800m=1300m=0.013hm

9km+280dam=9km+28km=37km=>0,37hm

62m+480dm=620dm+480dm=1100dm=>11000cm

4dm+ x dm= 1m => x=6dm

970mm+ X mm= 1m => x=30 mm

78m+9km+80dm-32hm= 78m+9000m+800m-320m= 9878-320=9550m

84km-17hm......hm 37 km

83 000 mm + 83 m - 300 dm -....... dm108m

140cm +60cm = 20 dm.

800cm +20dm = 1m

Sper ca te am ajutat
