I would multiply the decimal part of these numbers by 3/5.

So 5.2865 = 5: (3/5) x 0.2865 = 5:17 or 5 hours and 17 minutes.

Here comes an other attempt:

1 h = 60 min

Therefore:

$5.2865 \ h = 5\ h + 0.2865\ h = 5\ h + 0.2865\ h \cdot \dfrac{60\ min}h = 5\ h + 17.19\ min$

Thank you very much everyone. It had been a long time since I've had to mess with things related to clock time; so your help is very much appreciated.
