Answer 1

350 mg+450 mg=800 mg=8 dg

420 cg+38 dg=4,2 g+3,8 g=8 g

628 kg+1720dg=628 000 g+172 g=629 172 g

53 kg×6:2=53 kg×3=159 kg=1 590 000 dg

1t-1q-1 kg=1000 kg-100 kg-1 kg=899 kg

123 g+47 dag-19 g=123 g+470 g-19 g
=593g-19 g=574 g

1q-10 kg-13 000 g=100 kg-10 kg-13 kg=77 kg

(32 kg+420 dg)×5=(3200 dag+4,2 dag)×5
=3204,2 dag×5=16 021 dag

42 kg:7+36 hg:10=6 kg+3,6 hg
=6 kg+360 kg=366 kg
