Percentage / Multiplication in Shell Script

Hello,

I am trying to compute the percentage in a script as shown below:

Code:
PerCover=`echo "scale=2 ; 100  \* ($InputCover/$Total)" | bc`

However the PerCover value is blank/null. What do I need to do differently?

Thanks for your input!

You don't need bc to do this, just do the multiplication first.

Code:
echo "percentage:  $(( ($InputCover*100)/$Total ))"
