    For this question, theres an next way which is say:
    You have 2/3 and they say it’s = to x/24 you can make it equivalent. So divide both denominators and use the answer you get from dividing it and multiply it by the numerator.
    Eg. 4/8 = 24/x. Divide the numerators and multiply that answer to the denominator.
    4x6 = 24
    -- --
    8x6 48

  • @Monkchelle_Kongbama
    @Monkchelle_Kongbama 10 หลายเดือนก่อน

    I'll do you one simpler, no need for reducing or rewriting the problem
    The original problem is 4/6 = x/24
    so just multiply 4 * 24 then divide the result by 6
    x=16
    The standard name for this is a bit lackluster as it leaves out a major part of the operation. I learned it as "cross multiply and divide" which better gets the operations across to the learner as it tells you the only two things you _actually_ have to do to find your answer.
    This is by far the most useful math skill you will ever learn. It's the only one I still use in daily life. Usually when finding the percentage of something.

    Great! Here because “Mean Girls” the movie refers to this term. My way is exactly backwards but I can do it in my head while flying an airplane. Yes I did do 4/6= 2/3 then I divided 24 by. 3 = 8 . Then multiply 2*8 =16…>>> 16/24. Your dyslexic students might find this easier to do.
