1 hl = 100 l
100 * 80/100 = 80 l
80 * 6 = 480 l in 6 butoaie
100 : 2 = 50 l jumatate de butoi
50 * 2 = 100 l in 2 butoaie
480 + 100 = 580 l apa
580 l = 5,80 hl
100 * 80/100 = 80 l
80 * 6 = 480 l in 6 butoaie
100 : 2 = 50 l jumatate de butoi
50 * 2 = 100 l in 2 butoaie
480 + 100 = 580 l apa
580 l = 5,80 hl
