Need help converting h.mm to hh:mm (2.88) to 03:29 in SSRS expression

Hi all,

Is it possible to convert the following numeric(38,2) data type to hh:mm format in SSRS expression?

For example in column A I have the following records:

3.15

2.88

1.60

0.39

1.80

h.mm

The 3,2,1,0 before the decimal presents the hours only, and the 15,88,60,39,80 are the minutes. Not sure how to calculate it in order to produce it in time format hh:mm.

I appreciate any help,

Thanks in advance.
