Răspuns:

Explicație pas cu pas:

a)

500 kg = 5 q

1 kg = 0,01 q  ⇒ 500 kg = 500 : 100 = 5 q

820 q = 82000 kg

1 q = 100 kg ⇒ 820 q = 820 x 100 = 82000 kg

14000 kg = 14 t

1 kg = 0,001 t ⇒ 14000 kg = 14000 : 1000 = 14 t

34 t = 34000 kg

1 t = 1000 kg ⇒ 34 t = 34 x 1000 = 34000 kg

120 t = 1200 q

1 t = 10 q ⇒ 120 t = 120 x 10 = 1200 q

b)

2 t 7 q 3kg = 2703 kg

2x1000kg+7x100kg+3kg=2000kg+700kg+3kg=2703kg

5 t 9 q 45 kg = 5945 kg

5x1000kg+9x100kg+45kg=5000kg+900kg+45kg=5945kg

17 t 6 q 8 kg = 17608 kg

17x1000kg+6x100kg+8kg=17000kg+600kg+8kg=17608kg

23 t 8 q 25 kg = 23825 kg

23x1000kg+8x100kg+25kg=23000kg+800kg+25kg=23825kg

62 t 5 q = 62500 kg

62x1000kg+5x100kg=62000kg+500kg=62500kg
