Question

8 dl + ? cl =1 l
60 cl + ? dl = 1 l
? dl + ? cl =2 l
? cl + ? ml = 3 l

Answer 1

8 dl + 20 cl =1 l
1 dl=10 cl
8 dl=80cl
1 l=100 cl
100 cl-80 cl =20 cl

60 cl + 4 dl = 1 l
60 cl=6 dl
1l=10 dl
10 dl-6 dl=4 dl

10 dl + 100 cl =2 l
1 l= 10 dl
1 l= 100 cl

  150 cl + 1500 ml = 3 l
1 l= 100 cl
1 l= 1000 ml
