Cricket Stats - Balls Bowled

Hey guys, another question:

Im trying to put together a small cricket stat spreadsheet and hit another bump:

what i want to do is turn overs bowled into balls, so the forum needs to be something like this:

Example, one cell = 17.2 then in the Ball cell needs to equal 17 times 6 + 2

so the 17 needs to be times by 6 and then what ever the decimal point needs to be added to the sum of 17*6

I hope that made sense to everyone
