"Vi bor i det nionde huset till höger."

Translation: We live in the ninth house on the right.

It was not accepted when I wrote "den" before "femte" in this sentence: "Det är femte gången du ringer mig i dag." I do not see any structural difference between "den femte gången" and "det nionde huset". So, when do we use "den/det/de" before the ordinal numbers when they are followed by a noun, as well?

[Zmrzlina]

With ordinal numbers, it's optional. It should be accepted with "den femte gången" as well, although I think without sounds better.

Thanks.

Since hus has the et on the end indicating "the," is there any special rule when you also use "det"? Seems like sometimes it's there and sometimes not.

there is a bit explanation on the skill "adjectives 1". especially the section "definite forms": https://www.duolingo.com/skill/sv/Adjectives-1 i hope that helps.

[Nane.1982]

Would "Vi bor i nionde huset" be correct, too? If yes, does it sound better or worse without the "det"?
