    Josephine cuts an apple into thirds, she eats 1/3 herself and splits the rest between her rabbit and Guinea pig. Her rabbit gets 5/7 of the remaining apple and the Guinea pig gets the rest. What fraction of the whole apple does her Guinea pig get?

    I keep getting minus numbers 😭

    I don't know where else to ask since I've done loads of fractions questions just fine, I only have a problem with this one.

    No I think you're right in getting a negative answer. Are you getting -1/21 cause I think there's a mistake in the Q

    Okay, so she's eaten a third of the apple. There's 2/3 of the apple left that gets split between her rabbit and the pig.

    Now the rabbit gets 5/7 of the remaining (2/3) of the apple. This means the rabbit gets 5/7 * 2/3 of the entire apple.

    If the rabbit get 5/7 of the remaining apple, how much of the remaining apple does the pig get? What can you do with this number to get the fraction of the entire apple that the pig gets?

    "The rest" is 1-1/3=2/3 of the apple. If the rabbit gets 5/7 of the remainder, the guinea pig gets 1-5/7=2/7 of it. The remainder is 2/3 of the apple, as we just calculated. Thus the guinea pig gets 2/3*2/7 = 4/21 of the original apple.

    Also don't say "minus numbers"; it's "negative numbers".

    I may be making a blunder but if the rabbit gets five sevenths of two thirds then it gets 10/21;
    If the guinea pig gets two sevenths of the two thirds then it gets 4/21 which is more apple than is there?

    Edit: haha never mind, no one tell my advanced higher maths class I can't do fractions

    There isn't a mistake in the Q. Just a small catch.

    The person eats 1/3, let's call this 7/21 for ease.

    The rabbit eats 5/7 of the remaining apple. That is the key here. The remaining apple is 14/21, try solving now . 14/21 is worked out from 21/21-7/21 just for clarification

    7/21 (1/3) + 10/21 (2/3*5/7) leaves 4/21 left no negative numbers

    Thank you. That makes a lot more sense. I'll give that a go now. Would you say that the question is worded well or not?

    Look at my reply to your post. It's more complicated than what you tried to do...

    The question is worded perfectly well in my view.

    Actually I'm still getting it wrong. If I take 5/7 (or 15/21) away from 14/21 I'm still getting a negative answer.

    Well, it's more of an application question than bad wording, it's seeing if you can realise that if 1/3 of an apple is eaten then there can only be 2/3 left for everyone else . They can be tricky at first but make sure you read all the points next time . Have it a go and post your solution here

    READ MY POST. It's simply 2/3 times 2/7.

    By the way, please ignore the constellarknight person. He's just a troll, the maths forum is made up of much friendlier people than that, please don't be put off! He'll be sorted out in a moment.

    Try it again knowing that there is 14/21 left, and the rabbit pigs eats 5/7 of the 14/21 of the remaining apple. Leaving the gueina pig how much ?
