"Il a une vingtaine de chats dans son appartement."

Translation: He has about twenty cats in his apartment.

Nothing wrong with that!

I wrote: "He has like twenty cats..." and was marked wrong. Doesn't 'like' mean "about" in this context? Or is it too colloquial?

[John787925]

Sounds like a very good translation, but not the kind they'd include until users suggest it.

[PATRICKPIZ1]

probably considered a regional or generational expression.

[BruceEMellon]

Why une vingtaine and not simply vingtaine?

[WendyMcInt3]

yes please, can someone throw some light on this?
