14 kg+2q=
= 14 kg + 200 kg
= 24 kg
350 mg+450 mg=
= 800 mg
= 8 dg
420 cg+38dg=
= 4,2 g + 3,8 g
= 8 g
628 kg+ 1.720 dg=
= 628000 g + 172 g
= 628172 g
53 kg×6:2=
=53 kg × 3
= 159 kg
= 1590000 dg
1 t - 1 q - 1 kg=
= 1000 kg - 100 kg - 1 kg
= 899 kg
123 g + 47 dag - 19 g=
= 123 g + 470 g - 19 g
= 593 g - 19 g
= 574.g
1 q - 10 kg - 13.000 g=.
= 100 kg - 10 kg - 13 kg
= 90 kg - 13 kg
= 77.kg
