  1. DIVIDE 34 3/8 BY 3 1/8
    MULTIPLY 34 * 8 TO GET 272, ADD 3 TO GET 275/8
    THEN MULTIPLY 3*8 TO GET 24 AND ADD 1 TO GET 25
    NOW DIVIDE 275/8 BY 25/8
    YOU GET 11 DRESSES

  2. 34 3/8 divided by 3 1/8 =
    275/8 divided by 25/8 =
    (275/8) * (8/25) = 2200/200 = 11

    A simpler way would be to change the fractions to decimals.

    34.375 / 3.125 = 11
