    Elementary math

    Hello,

    I have a question which I tried to solve but not sure of my answer. Here's the question:
    Names for the same:
    Kathy and Gale are playing a game with pattern blocks. Kathy gives fraction rules and Gale uses the clues to determine what one whole is.
    Here are Kathy's clues:
    12 green blocks are 12/18ths. Gale thinks 3 yellow blocks are one whole. Is Gale correct? Show your work.

    My answer:
    Fraction of green blocks : 12/18 which means there are 12 green blocks out of 18 blocks.
    Total number of blocks: 18
    Number of non-green blocks : 18-12=6
    So, the fraction of non-green blocks: 6/18. Simplify 6/18=1/3
    So 3 blocks does makes one whole.
    But 3 yellow blocks does not.

    Thank you,
    want to learn

    Does the problem state that all of the blocks are either green or yellow? You don't say that and your problem makes no sense without some information like that.

    Thank you.
    No, the problem does not state that the blocks are either green or yellow. Maybe, I should assume that there are only green and yellow blocks because those are the two colors mentioned in the problem.

    Do we know for certain that there are 18 blocks? Or are you assuming that because the green blocks = 12/18ths?
    In the problem it says "Gale thinks 3 yellow blocks are one whole" Is this correct?
    If there are 3 yellow blocks then it looks to me like there are a total of 15 blocks. Are we trying to find out what one yellow block is equal to if it takes 12 green and 3 yellow to equal one whole?
