Answer 1

Răspuns:

350 mg + 450 mg =

= 800 mg

= 8 dg

420 cg + 38 dg=

= 4,2 g + 3,8 g

= 8 g

628 kg + 1720 dg =

= 628000 g +:172 g

= 628172 g

53 kg×6:2 =

= 53 kg× 3

= 156 kg

= 1560000 dg

1t- 1q - 1 kg =

= 1000 kg - 100 kg - 1 kg

= 900 kg - 1 kg

= 899 kg

123 g + 47 dag - 19 g =

= 123 g + 470 g - 19 g

= 593 g - 19 g

= 574 g

1 q- 10 kg - 13 000 g =

= 100 kg - 10 kg - 13 kg

= 90 kg - 13 kg

= 77 kg

(32 kg + 420 dg) x 5 =

=(3200 dat + 4,2 dag) × 5

=3204,2 dag × 5

= 16021 dag

42 kg : 7 + 36 hg : 10 =

= 6 kg + 3,6 hg

= 6 kg + 0,36 kg

= 6,36 kg
