a= 1. 0 l
2. 41.000 ml
b=1. 2 kl
2. 30 hl
a 2000cl-200dl=?l
2000cl=20l
200dl=20l
20l-20l=0l

4500cl-4000ml=?ml
4500cl=45000ml
45000ml-4000ml=41000ml
b.(80hl+600dal):7=?kl
80hl=8kl
600dal=6kl
(8kl+6kl):7=14kl:7=2kl
[7kl+(2200dal-20hl)]:9=?hl
7kl=70hl
2200dal=220hl
[70hl+(220hl-20hl)]:9=
(70hl+200hl):9
270hl:9=30hl
