Question

Afla ce lipsește din fiecare operație pentru ca egalitățile sa fie adevărate. 3dl+?dl=1l 40cl+?cl=1l 400ml+?ml=l 95cl+?cl=1l 1l=60cl+?cl 1l=1dl+?dl 1l=455ml+?ml 1l=655ml+?ml

Answer 1

1l=10dl
10-3=7
3dl+7dl=10dl=1 l(1l=10dl)

1l=100cl
100-40=60
40cl +60 cl=100 cl=1 l(1l=100cl)

1l=1000 ml
1000-400=600
400ml+600 ml=1000ml=1 l(1l=1000 ml)

1l=100cl
100-95=5
95cl+5cl=100cl=1l(1l=100cl)

1l=100cl
100-60=40
60cl+40cl=100cl=1l(1l=100cl)

1l=10dl
10-1=9
1dl+9dl=10dl=1l(1l=10dl)

1l=1000ml
1000-455=545
455ml+545ml=1000 ml=1l(1l=1000ml)

1l=1000ml
1000-655=345
655ml+345 ml=1000ml=1l(1l=1000ml)
