Question

Transforma si calculeaza atent unitatile de masura?58 000 kg +700 q=?t
400 ddal -100 dal=?hl=?kl
20 ani x100 =?secole=?milenii
900 000 min:6=?dm=/dam

Answer 1

30 hl = 3 kl 
20 secole = 2 milenii
la ultima banuiesc ca e metrii 
1500 000 dm= 15 000 dam 

Answer 2

58000 kg+700 q=58 000 kg+70 000 kg=128 000 kg=128 t (1 q=100  kg si 1 t=1000 kg )
400 ddal- 100 dal=8000 l-1000 l=7000 l=70 hl=7 kl (1 ddal=20 l....1dal=10 l...1 hl=100 l...1 kl=1000 l )
20 ani*100=2000 ani=20 secole=2 milenii
