Converting a Number into Minutes:Seconds

[HappsLucks]

OK, so it's Monday morning and I obviously cannot see the wood for the trees. This should be so simple, yet I am stumped.
Somebody out there please put me out of my misery.

An operator enters a recorded time on Sheet 1 (The data input sheet)
He enters the time from an instrument display, and enters 3 values, measured in minutes and seconds.

Input 1 = 4.52 (4 minutes and 52 seconds - the decimal point is used for a specific reason)
Input 2 = 4.45
Input 3 = 5.02
(The above fields can be any format, as long as the operator enters "number dot number")

On another sheet (The Results Output Sheet), I need to see the following: (Remember, the times are entered as minutes and seconds).
Time 1 = 4:52
Time 2 = 4:45
Time 3 = 5:02
Average Time = 4:53

For the life of me, I cannot seem to get this to work. Please provide formulae (if required) and range formats.
Thanks, appreciated.

Unless its formatted as text of course...

Thanks to all and sundry. Much obliged.

I found that Steve The Fish seems to have it nailed. I'm sure the other work also.

=TIME(0,INT(A1),MOD(A1,1)*100)

Thank you.

So this is what I have, seems to work for me.
