    don't make a wild guess. This is MATHS - it is a rational process work it out subtract 0.12 from each side of the equation

    @west_coast you have no way of knowing if @paolaxx33 just guessed that. MANY answers given by people here are just plain WRONG

    hmmm - well you need to try again r + 0.12 = 0.20 so subtract 0.12 from each side: r = 0.20- 0.12

    r + 0.12 = 0.20 -0.12 -0.12 r=0.08 To check you just add 0.08+0.12= 0.20 @west_coast
