Answer 1

a) 61 g = 610 dg

c) 350 mg = 35 cg

e) 4700 kg = 47 q

g) 450 q = 45 t

b) 680 g – 120 g = 560 g

d) 680 dag – 100 dag = 580 dag

f) 470 hg – 21 hg = 449 hg

Answer 2

a) 27 g • 10 =270 dg
34 g • 10 = 340 dg
*270 dg • 340 dg = 610 dg*
c) 50 mg : 10 = 5 cg
300 mg : 10 = 30 cg
*5 cg + 30 cg = 35 cg*
e) 4 200 kg : 10 = 420 q
500 kg : 10 = 50 q
*420 q + 50 q = 470 q*
g) 420 q : 10 = 42 t
30 q : 10 = 3 t
*42 t + 3 t = 45 t*
b) 12 dag • 10 = 120 g
*680 g - 120 g = 560 g
d) 68 hg • 10 = 680 dag
*680 dag - 100 dag = 580 dag*
f) 47 kg • 10 = 470 hg
210 dag : 10 = 21 hg
*470 hg - 21 hg = 449*
