"I am drinking, you are drinking."
Translation:Ich trinke, du trinkst.
if you want to be complete correct: "i am drinking, you are drinking" is present continuous. i am german and i have learned, that the ing-form is something i do right now. so i am drinking right now. this means "ich bin gerade am trinken." if i say "i drink" then it says "ich trinke". this is something i do often, or generally. "i often drink" "ich trinke oft" but "now i am drinking" "jetzt gerade bin ich am trinken". (this is very difficult, bin i hope you understand what i am saying)
trinkst is used when the subject is du -- du trinkst = you are drinking (when speaking to one person)
trinkt is used when the subject is one of er, sie, es or ihr or a singular noun -- der Junge trinkt "the boy is drinking", ihr trinkt "you are drinking" (when speaking to several people at once), er trinkt "he is drinking".
German does not have a continuous aspect. See the final section of the tips and notes for the first unit: https://www.duolingo.com/skill/de/Basics-1/tips-and-notes
English needs a helping verb to form the present continuous tense; you have to say "I am drinking".
But when you translate that into German's present tense, it's just a single word: ich trinke. No helping verb needed or possible.
Similarly, "you are drinking" is du trinkst.
You cannot translate word for word because German grammar is not the same as English grammar.

doesn't "trinken" mean are drinking?
trinken is the verb form for wir and sie (they) -- so "we are drinking is wir trinken and "they are drinking" is sie trinken*.
But here, the subject is not wir or sie; it's either du (if "you" refers to one person) or ihr (if "you" refers to several people). So the verb form has to be either du trinkst or ihr trinkt.
You can't always translate "are drinking" into the same verb form, because German does not use the same verb form for "you" as it does for "we" or "they".
What's the difference between ihr and du?
Use du when you are speaking to one person whom you know well.
Use ihr when you are speaking to several people at once whom you know well.
They are both informal, but one is singular and the other is plural -- like the difference between "I" and "we" or between "he" and "they".
why is du correct and not ihr?
They are both correct, since "you" in English is ambiguous.
Just remember to use the right verb form for each subject, e.g. du trinkst with -st but ihr trinkt with -t.
Why is "ihr trinken" not accepted
Because it is not correct. The subject ihr and the verb form trinken do not match.
Verb forms for ihr end in -t, so "you are drinking", when speaking to several people, is ihr trinkt.
trinken is the verb form for wir (we) and sie (they).
how to know the exact meaning like "i drink "or" i am drinking"?
From context -- are you talking about a repeated or habitual action, or one that is taking place right now?
Without context (as with a single Duolingo sentence), you can't tell which of those translations is more appropriate. In that case, just pick one -- both will be accepted.
