auto search for rate

[plantslayer]

I have been provided dollar value and I need to find out the rate.
Example:
Gross Pay EI
$840. 14.53
Now after fiddling with numbers I found the rate to be 1.73%. What is the
formula that can automatically calculate this?

=EI/Gross_pay
or

=14.53/840

Thanks, feel silly for asking question.
