Translation of "sixth" into Slovak

You mean that Henry had to answer when he broke the sixth commandment?

Myslíte, že aj Henrik sa zodpovedal keď porušil šieste prikázanie?

In fact, to see at night, it needs only one sixth as much light as humans do.

Na nočné videnie potrebuje iba šestinu svetla, ktoré potrebujú ľudia.
