Hey guys. I just started learning Esperanto through an email course and Lernu! So i had to do some translations. I just want to know if they are correct, because i'm in doubt if i should put -n on the objectives (If they are objectives):
Sixty minutes are one hour. = Sesdek minutoj estas unu(n?) horo(n?).
Twenty-four hours are one day (and night). = Dudek kvar horoj estas unu(n?) tago(n?).
If there are other mistakes then please tell me Thank you for your time.
