code i've tried
What am i doing wrong ?

Code:
sum1=$((add1 + add2))
echo "Success = $sum1"
sum2=$((add3 - add4))
echo "Attempts = $sum2"
final="scale=4; ($sum1 / $sum2 ) * 100" | bc
echo " Success rate = $final"

No percentage is worked out, it only is printing Sum1 and Sum2 values.

Code:
Success = 7513
Attempts - custom = 9150
Success Rate =

what i'm expecting is the below output.

Code:
Success = 7513
Attempts - custom = 9150
Success Rate = 82.10
