Answer 2

5l.............4kg
1 l............x kg
x=4×1/4=4/5=0,8 kg
deci 1 litru de ulei=0,8kg

a) 0,8kg......................1 litru
    x kg.......................12 litri
x=0,8×12/1=9,6 kg
deci intr-o caldare de 12 litri incap 9,6 kg

0,8 kg...............1litru
x kg..................180 litri
x=0,8×180/1=144kg
deci intr-un butoi de 180 litri incap 144 kg

1litru...................1000ml

1000ml...................0,8kg
250ml.....................x kg
x=250×0,8/1000=200/1000=0,2kg
deci imntr-un pahar de 250 ml incap 0,2 kg
