9/10Y = 36
What is Y

  • algebra - ,

    9/10Y = 36

    Y = 36/(9/10)
    Y = 36 * (10/9)
    Y = 360/9
    Y = ?

  • algebra - ,

    The answer of Ms,Sue is wrong.


    9 / 10 Y = 36 Multiply both sides with 10 Y

    9 = 36 * 10 Y

    9 = 360 Y Divide both sides with 9

    1 = 40 Y Divide both sides with 40

    1 / 40 = Y

    Y = 1 / 40

    Y = 0.025

  • Ms Sue is right - algebra - ,

    tom wrote
    9/10y=36

    according to the order of operations,
    we only divide by 10 or else Tom should have said

    9/(10y) = 36

    so Ms Sue took it exactly the way it was written and her answer is correct.
