Seven and five is twelve. If you say, 'seven and five are twelve', you are actually saying that the number 7 is 12, and the number 5 is 12, which is impossible.
'twelve' in french is 'douze'
Elle a douze ans.
twelve point five
j'ai douze ans
Twelve and thirty five thousandths.
twenty five is 'vingt cinq' in French.
Well, you might add 12000 + 1200 + 12, but that is not the normal way to name this number. Usually you say "twelve hundred" if there are no higher digits.
twenty-twelve (2012) is "deux-mille-douze" in french. I'm trying to figure out whether you can say "vingt-douze", which would be the literal translation of twenty-twelve, but it seems this is not something that translates directly.
cinq (sank) - five
J'ai douze ans.
Twelve thousand, five hundred sixty.
