Question

Calculeaza : 7t + 7 kg = ? kg , 9 q + 500 kg = ? kg 400 kg + 7 q = ? q 2 t + 80 q = ? t , 8 g - 3000 mg =? g , 300 mg - 2 g = ? dg , 1 g - 100 cg = ? cg , 9 kg - 5000 g = ? g , 2000 kg + 90 q = ? t , 7000 g - 20 hg = ? kg , 8 x15 dg = ? g , 900 q : 5 = t

Answer 1

7t+7kg=7000kg+7kg=7007kg
9q+500kg=900kg+500kg=1400kg
400kg+7q=4q+7q=11q
2t+80q=2t+8t=10t
8g-3000mg=8g-3g=5g
300mg-2g=3dg-20dg=-17dg
1g-100cg=100cg-100cg=0cg
9kg-5000g=9000g-5000g=4000g
2000kg+90q=2t-9t= -7t
7000g-20hg= 7kg-2kg=5kg
8x15dg= 120dg=12g
900q:5=180q=18t
