"A nagy fehér hajó körül száz hal úszik."

Translation: A hundred fish swim around the big white ship.

[Evolita]

I don't think we should start this sentence with an "A"

[mizinamo]

Which sentence, the Hungarian one or the English one?

[Evolita]

the English one

[mizinamo]

It needs to be either a hundred or one hundred - see e.g. http://english.stackexchange.com/questions/10521/why-should-i-say-one-hundred-when-hundred-seems-enough .

[Evolita]

Yes, thank you!

[bnyugat]

One hundred!!! Yes, I've reported it again and again.

How do we know 100 fish are swimming around the boat instead of a boat sailing around 100 fish?

[jzsuzsi]

A boat is sailing around the 100 fish: A száz hal körül egy hajó úszik. Or A száz hal körül úszik egy hajó.

Different word order. Körül is a postposition, so X körül = around X.
