    you do the difference divided by original weight
    so 6/84 x 100 = 7.14% decrease in weight

    but the difference is 8? and im looking for increase confused lol

    its about 10.5% which gave me 83.98. dont know how i worked it out

    Exactly except the difference is 84 - 76 = 8 so actually a 10.5% increase in weight

    10.524%

    so let me get this straight lol the difference between 76 and 84 is 8
    divide 8 by 76
    and times the answer by 100
    which = 10.526316

    yep

    Oh oh sorry was rushing off

    8/84 x 100 = 9.5%

    You divide by 84 because 84 is the original number and you want to find the percentage decrease of that number, not the final figure

    Sorry but your numbers are wrong also.

    The answer is not calculated using the difference. It's the percentage increase above 76 were 76 is 100%.

    It is 84 / 76 * 100 = 110.526% so the difference is 10.526%

    10.526% is the answer

    I'd give up if I was you! both your answers were completely wrong.A = 84B … I'd give up if I was you! both your answers were completely wrong.A = 84B = 76to work it out :-((A / B) -1 *) 100 = Percentage changeAww so it is, think i just need to go sleep :)The numbers are right though

    Mrs.z should give up as both answers were wrong!

    Anyway,

    Assign A = 84, B =76

    percentage change = ((A / b) -1) * 100
