Calculati si efectuati transormarile :

a)
27g + 34 g = ? dg
b) 680 g - 12 dag = ? g
c) 50 mg + 300 mg = ? cg
d) 68 hg - 100 dag = ? dag
e) 4200 kg + 500 kg = ? q
f) 47 kg - 210 dag = ? hg
g) 420 q = 30 q = ? t
h) 300 cg - 12 dg = ? dg

Multumesc anticipat

A) 270dg+340dg=610dg
ai transformarile in carte le faci dupa model
d) 680dag-100dag=580dag
e) 42q+5q=47q
f)470hg-21hg=449hg
g)42t+3t=45 t
h) 30dg-12dg=18dg
