    percentage help

    If the size of the UK is 244 820km square and the amount of rainforest cut down per year is 244 3392km square what would be the percentage of the rain forest cut down per year?

    You would need to know the total area of rainforest, the size of the UK
    has nothing to do with this question as asked.

    I think that may have just been a typo. He/She probably meant to say what percent of the UK would be cut down per year which I think would be:

    \frac{2443392}{244820} Which is already greater than 100%.

    Unless that extra 3 was also a typo then it would be

    \frac{244392}{244820} \approx 99.8

    In other words it would just be \frac{\text{Area cut down per year}}{\text{Size of the UK}}

    Since the question is:

    "what would be the percentage of the rain forest cut down per year?"

    we should not try second guessing the real question, but make clear that
    the question asked makes no sense. That way the original poster may
    learn something other than the answer to their question, and that is that
    it is important to make their meaning clear.

    It is what my supervisor taught me, and what his supervisor was well known
    for.
