    1 1/4x = 3/4

    5/4x = 3/4

    x = (3/4) / (5/4)

    x = 3/4 * 4/5

    x = 12/20 which reduces to 3/5

    check ...

    1 1/4 * 3/5 =

    5/4 * 3/5 =

    15/20 reduces to 3/4

    so u would multiply 1 1/4 by 3/5 to get 3/4

    I'd suggest dividing. so, what you do is you put 5/4 x 4/3 (thats how dividing works) and you get 20/12 which, when simplified, is 1 2/3.
