Question

Calculeaza:
720 cl - 40 dl=dl
620 hl-380 dal= hl
700 ml + ? Cl = 1 l
5 dl + ? Cl= 1 l
40 cl + ? Dl=1 l
? Ml + ? Ml = 1 l

Answer 1

720cl -40dl= 72dl-40dl=32dl
620hl-380dal=620hl-38hl=582hl

700ml+? cl=1l
1l-700ml= 100cl-70cl=30cl

5dl+ ?cl=1L
1L-5dl=100cl-50cl=50cl

40cl+?dl=1L
1L-40cl=10dl-4dl=6dl

?ml+?ml= 1L
500ml+500ml=1000ml=1L

Answer 2

* 720 cl - 40 dl = 72 dl - 40 dl = 32 dl
* 620 hl - 380 dal = 620 hl - 38 hl = 582 hl
* 700 ml + 30 cl = 1 l
  700 ml = 0,7 l
  30 cl = 0,3 l
* 5 dl + 50 cl = 1 l
  5 dl = 0,5 l
  50 cl = 0,5 l
* 40 cl + 6 dl = 1 l
  40 cl = 0,4 l
  6 dl = 0,6 l
* 500 ml + 500 ml = 1 l
  500 ml = 0,5 l
