    Need help solving this problem with fractions

    Can someone help me and give me a step by step to solve the following?

    147/20/2-x = 147/10

    So 147 over 20 over 2-x equals 147 over 10.

    Please correct me if I'm wrong. It sounds like your equation is
    \frac{147/20}{2 - x} = \frac{147}{10}

    If that's correct first note that you can cancel out the 147 from both sides. That leaves you with
    \frac{1}{20(2 - x)} = \frac{1}{10}

    Flip this equation upside down and solve for x

    147/20/2-x = 147/10

    147/20 (2-x) = 147/10
    147/20 1/(2-x) = 147/10
    147/20(2-x) = 147/10 divide by 147 to both sides
    1/20(2-x) = 1/10
    20(2-x) = 10 ---------- divide by 10
    2(2-x) = 1
    4 2x = 1
    2x = 3
    x = 3/2

    Is there an echo in here?
