Răspuns:

Explicație pas cu pas:

1 kg = 1000 g

7 kg = 7000 g

2kg si 1/2 kg = 2,5 kg = 2500 g

2 kg = 2000 g

1/2 kg = 0,5 kg = 500 g

3 kg si 1/4 kg = 3250 g

3 kg = 3000 g

1/4 kg = 0,250 kg = 250 g

3/4 kg = 3·0,250 kg = 0,750 kg = 750 g

Answer 2

Salut!

1kg=1000g

7kg=7x1000=7000g

2kg+1/2kg=2,5kg=2,5x1000=2500g

3kg+1/4kg=3,25kg=3,25x1000=3250g

3/4kg=0,75kg=0,75x1000=750g

Succes!
