Question

Exercițiul 2 dau coroana

Answer 1

→ 1740dm = 1,74 km
27 dam = 0 , 27 km
15 hm = 1 , 5 km
5600 cm = 0 , 56 km
2000m = 20 km


lungime traseu = 1.74 + 0.27+1.5+0.56+20 = 24.07 km

→ Alexandra 
250 hg = 25 kg
1200dag = 12 kg
Alexandra = 25+12=37 kg

Teodor
1500 g = 1 , 5 kg
150 dag = 1 , 5 kg = 1500 g
Teodor = 1500+1500=3000 g = 1,5+1,5 = 3kg


Irina 
150000cg = 1500 g
12500dg=1250 g
Irina = 1500+1250= 2750 g

→1500ml = 150 cl = 1 , 5 l
50 cl = 0,5 l
10 dl = 100cl = 1 l

1500ml+50 cl +10 dl = 300 cl = 3 l

→ 10:20-13.05 = 2 ore si 45 minute

→2 ore si 45 min + 2x15= 3 ore si 15 minute


sper ca e bine !! coroana ??
