Răspuns:

a) 150 dam + 470 dam =620dam=6200m

3000m-50dam=350dam

3×710dam=2130dam

b) 35 l+19dl=369dl

73dl+87dl=16l

1000dl;10=100dl=1000cl

c) 100kg-500g=995 hg

3×120g=36dag

500kg:5=100kg=100000g

Salutare!

a)

150 dam + 470 dam = 620 dam = 620 • 10 = 6200 m

3000 m - 50 dam = 300 dam - 50 dam = 250 dam

3 • 710 dam = 2130 dam

b)

35 l + 19 dl = 350 dl + 19 dl = 369 dl

73 dl + 87 dl = 160 dl = 16 l

1000 dl : 10 = 100 dl = 1000 cl

c)

100 kg - 500 g = 100000 g - 500 g = 99 500 g = 995 hg

3 • 120 g = 360 g = 36 dag

500 kg : 5 = 100 kg = 100000 g
