Pension Calculation Formula Needed

[Sunfud01]

This has been doing my head in all weekend!

My Pension is to be paid using the following equation:

Multiply "Pensionable Earnings" by "Reckonable Service" by 1/80th

I can not work out how to write the Formulas to do it?

Please can somebody help?

Thank you

assuming
Pensionable Earnings = a2
Reckonable Service = b2

(b2/80) = 80th of Reckonable Service
=A2*(b2/80)

you dont need brackets really
A2*B2/80

unless you mean something else
