    Changing ratio

    Hi,
    I am really stuck in this ratio question.
    Josie makes fruit punch by mixing juice and lemonade in the ratio 2:5. She needs to make 42 liters of punch for the party. How much ingredients does she need. (I can do this bit) 12 liters of juice to 30 liters of lemonade.
    To make the second batch of punch go further Josie adds 2 more liters of lemonade. What is the new ratio? I know that answer is 8:22 but I have no idea of how they got this answer.
    Please help
    Regards Lawrence

    I would say the answer you have quoted is incorrect. What do you say the answer is?

    Re: Changing ratio

    What I'm saying is: the answer is not 8:22. This might be the answer the book gives, but it is not correct.

    What do YOU get as your answer to the question?

    Then I'll tell you if I agree with you.

    Re: Changing ratio

    I thought the answer would be 12:32. Which would be 3:8
