1. 3l=30dl=300cl=3000ml
40dl=4l=400cl
300cl=30dl=3l
2000ml=20dl=2l=200cl
8kl=800dal=8000l=80hl
50dal=500l=5hl
70hl=7kl=700dal=7000l
2.8dal+70dal+300dal=378dal
5l+30l+3l=38l
9cl+20cl+300cl=329cl
3.x-cantitatea din primul butoi
2x-cantitatea din al 2-lea butoi
x+2x=300l => 3x=300l =>x=100l vin
Deci primul butoi are 100 l vin si al 2-lea are 200l vin( adica dublu)
