How to write...?

[student95]

I want to say that I've been studying Japanese for 3 years (and still am)　in response to the question 'how long have you been studying Japanese?

Would the question be どのぐらい日本語を勉強していまか。 or どのぐらい日本語を勉強していましたか。

Likewise, would this answer make sense?
日本語を三年ぐらい勉強していました。　(As I want to say I have been studying and not that I have studied)
or　日本語を三年間ぐらい勉強していました。

Good questions (because these tenses are everyone's weak points).

Both the question and answer need to have います in them, NOT いました. If you use いました, you have already quit studying Japanese.

Ｑ：「今まで（ＯＲ　もう）どれくらい日本語を勉強し ていますか。」

Ａ：「３年くらい勉強しています。」

Another VERY natural way of saying these :
(In fact, this would be the native speaker's choice.)

Ｑ：「日本語を勉強して（もう）どれくらいになります か。」

Ａ：「（もう）３年くらいになります。」
