So, what do you think?

i would think is c but I am sure its wrong
 
If you can explain your choice, it will be obvious I'm sure.
 
1cm=10dm
1cm/3= 1000dm/3 (since 10^3=1000)
1dm=1L
1000dm/3=1000L

Therefore your task here is to multiply 1.5 by the equivalent of 1 cm/3 in Liters :)

No. 1dm=10cm

1cm/3= 1000dm/3 (since 10^3=1000)

You started with the wrong assumption, so this is wrong as well. Note that 1cm/3 and 1cm3 are two different things. I suppose you wanted to write cm^3.

1dm=1L

And miraculously this is correct.

Oh yeah, I did make a few mistakes. Fortunately, I remembered and put down the concept of what had to be done.
