Question

Transforma in unitatile de masura indicate: 30m și 5 dam=?dam;800mm și 9cm=?cm;97kmși6dam=?m;42000dmși120m=?dam​

Answer 1

30m si 5 dam=?dam

30m=30:10dam=3dam

3dam + 5dam = 8 dam

30m si 5 dam= 8dam

800mm si 9cm=?cm

800mm=800:10cm=80cm

80cm + 9 cm = 89cm

800mm si 9cm= 89cm

97km si 6dam=?m

97km=97•10³m=97000m

6dam=6•10m=60m

97000m + 60m = 97060m

97km si 6dam = 97060m

42000dm si 120m=?dam

42000dm=42000:10²dam=420dam

120m=120:10dam=12dam

420dam + 12 dam = 432dam

42000dm si 12m= 432dam
