125 x 10 mc = 1250 mc
1mc = 1000 l
1250 mc = 1250000 l
1250000 l = 1250 kl
1mc = 1000 l
1250 mc = 1250000 l
1250000 l = 1250 kl
[tex]125 \cdot 10 \ m^3=1250 \ m^3 \\ 1 \ l=1 \ dm^3 \\ 1250 \ m^3=1250000 \ dm^3 \\ \Rightarrow 1250000 \ dm^3=1250000 \ l \\ 1 \ kl=1000 \ l \\ \Rightarrow 1 \ l=0,001 \ kl \\ \Rightarrow \boxed{1250000 \ l=\boxed{1250 \ kl}}.[/tex]
