Question

Va rog sa ma ajutati !! La tema de la matematica am 10 exercitii dar nu stiu 2!! Va rog sa ma ajutati !!
1).
a). 4,5g + 12dg + 1,35hg = ( in dag) b). 13,4dg + 10,5cg + 4,5g = ( in mg)

c). 145g + 3,2kg +7534dg = ( in hg ) d). 18,4dag - 4,5dg = ( in g )

e). 5t + 3,2q - 7500 hg = ( in kg) f). 5,42003kg + 27000mg + 4,5g = ( in dag )

2).
a). 3m + 0,12km + 50000cm = ( in dam) b). 4,13cm + 3000mm + 2,7565dam = ( in m )

c). 3,4dm + 0,007hm + 16cm += ( in dm ) d). 5hm + 12,3dam = ( in km )

Answer 1

a)0,45dag+0,12dag+13,5 dag=14,07 dag
b)1340mg+105 mg+4500mg=5945mg
c) 1,45hg+32hg+7,534hg =40,984 hg
d)184 g+0,45g=184,45 g
e)5000kg+320kg-750 kg=4570kg
f)542,003 dag +2,7 dag =544,703 dag
2) a) 0,3 dam +12 dam +50 dam =62,3 dam
b) 0,13 m+3m+27,565 m=30,695
c)3,4 dm+7 dm +1,6 dm=12 dm
d) 0,5 km +0,123=0,623 km
