Excel Formula minutes convert to hours

Hi does anyone know the formula for excel so it will add the minutes after
the decimal and convert them to hours.

Need to check my log book times and make a database off information types
flown etc.

EG

1.33
1.56
=2.89

Needs to say 60 mins is one hour

so

1.33
1.56
=3.29

???????????????

=SUM(E1:E23)

=IF(A31000,TIMEVALUE(LEFT(A3,1)&":"&RIGHT(A3,2)),T IMEVALUE(LEFT(A3,2)&":"&RIGHT(A3,2)))
The formatting of the cells in column B is HH:MM.

Thanks Mal
