A good response to this is, "Thanks, I will."
Similarly, what should I say when people say what's up?
As a greeting: "What's up?" or here (West Midlands of England) commonly just "sup" is a general greeting, you can response with answers like "Not much", "Nothing", "Alright" etc. In this context, the response is just a return of the greeting, or a confirmation that all is going normally.
Also to know, how can I help you answer?
It's what is called a closed question, because the only possible answers are "yes" or "no" (with a "please" or "thank you" thrown in for politeness' sake). True, but you can avoid a no by saying: I'm fine/all right, thanks.
What means of keep it up?
phrase. If you keep it up, you continue working or trying as hard as you have been in the past. There are fears that he will not be able to keep it up. You're doing a great job! Keep it up!
What's the best reply for thank you?
- How thoughtful.
- I couldn't have done it without you!
- No worries!
- No … Thank YOU!
- You're welcome. The absolute classic!
- Don't mention it.
- It's nothing.
- It's my pleasure. This one is a little like the others on this list, but don't use it for simple things, like when someone thanks you for passing the salt.
