I don't know if this is the correct place for this question but here goes. This might be a very obvious question but if for example I have a wage of £23000 after paying tax at 25%, what is the gross pay? I thought that if I did 25%x = 23000, then x would equal 23000/0.25 but that give a ludicrous figure of 92000. So obviously that isn't correct. What is the correct method?
