    ( 15 / 4 ) / ( 9 / 1 ) =

    15 * 1 / ( 4 * 9 ) =

    15 / 36 = 3 * 5 / ( 3 * 12 ) = 5 / 12


    15 / 4 divided by 9 / 1 = 5 / 12

    Remember this:

    division is the reciprocal of multiplication, "IS" means equal, or the same.

    15/4 divided by 9/1 equals 15/4*1/9
    = 15/36 and that can be reduced
    =3*5/3*12=5/12

    a/b divided by c/d= a/b * d/c =ad/cb
