Question

ex 3 plsss repede model:12dm=?mm
12dm=(12×100)=1200mm
12dm=1200mm

Answer 1

a) 
700 kg = ( 700 × 100 ) dag = 70 000 dag 
1 500 kg = ( 1 500 × 10 ) hg = 15 000 hg 
2 400 hg = ( 2 400 × 100 ) g = 240 000 g 

b) 
6 000 mg = ( 6 000 : 1 000 ) g = 6 g 
5 600 mg = ( 5 600 : 100 ) dg = 56 dg 
8 600 mg = ( 8 600 : 10 ) cg = 860 cg 

c) 
14 600 kg = ( 14 600 × 10 ) hg = 146 000 hg 
140 hg = ( 140 : 10 ) kg = 14 kg 
1 500 dag = ( 1 500 : 100 ) kg = 15 kg
