Answer

Hey hammoudlearn82!

The sentence is expressing the idea of some casual - which means: not serious, natural, not formal - and much more common - which means: day-by-day, familiar, frequently - way to ask someone how he/she is doing.
It means that there are some more natural ways to have an informal (and casual) conversation, instead of sounding too much serious.

I hope this helps!

Answer

Answer

Your sentence doesn't mean much without context. We can't even tell what "these ways" refers to without you telling us what it means.

Best of luck with your studies!
