Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Otras"

A: The most common way (informal way) to say how are you? would probably be “How’s it going?” or “How are you doing?” (How ya doin’?) to which you could respond with “it’s going well” or “fine/good”

You could also add “hey”
-Hey, how’s it going? (Casual)
-It’s going fine, how ‘bout yourself?

Of course you could also say “what’s up?” to which you could respond with a phatic “hey” or “what’s up” OR with a “Nothin’ much” or “nothin much, I’m just working on an assignment for my physics class” (and you can say whatever you are up to)

There are lots of other ways, but I’ll just leave you with these options lest I overwhelm you with phrases 😅
