    Hello, I'm finding this question quite hard:

    "Calculate the overall percentage change, stating whether it is an increase or a decrease. An 12% increase then a 12% decrease."
    I understand that you would change then to their multipliers so 12% increase= x 1.12 and 12% decrease = x 0.88
    Then you multiply the multipliers so 0.9856 but I'm really confused as to what you do next? Any help would be greatly appreciated!

    Is 98.6% more or less than 100%?

    The core point here is that you multiply some figure or other by 1.12 which increases it by 12%. Whe you multiply the new figure by 0.88 you are decreasing it by 12% but it is now a bigger figure and so 12% of it is larger than the 12% of you original figure was.

    Try it with a really big percentage to see. Increase £8.00 by 50% and then decrease the new figure by 50%.

    £8 * 1.5 = £12 (as expected)
    £12 * 0.5 = £6 i.e. Smaller than £8.

    If you are having difficulty with a problem then try to do the same problem with really easy figures to see what is happening more clearly.

    Wow thank you both so much, I realise how simple that is now. I don't know why I was making it more complicated. Thanks again!
