Answer 2

It looks like you provided the number "6300:30" without any context. However, I assume you might be referring to a time duration written in hours and minutes.

If "6300:30" represents a time duration, it can be converted to a more conventional format. Here's the conversion:

6300 minutes + 30 seconds = 105 hours, 0 minutes, and 30 seconds.

If you need the time duration represented in a different format or if you were referring to something else entirely, please provide more context or clarify your question, and I'd be happy to assist further. Additionally, I'm not sure what you mean by "столбики пожалуйста," as it seems to be in Russian, but I'm here to help with any questions or concerns you may have.
