  1. Nr = 16/21 and deno. = 4/21 so fraction = 16/4 =4.


  2. the answer is 4.

    You can add 3/7+1/3 = 9/21+7/21 = 16/21

    then add 1/21+4/28 = 1/21+3/21 = 4/21

    Now you got 16/21 over 4/21 that equals 16/4 that equals 4 !

  3. numerator: 3/7+1/3= 16/21

    denominator: 1/21+4/28 = 1/21 + 1/7 = 4/21

    16/21 over 4/21 = 16/21 * 21/4 = 4
