23. 7/9 divided by 1/7= 5 4/9

    # 15 is incorrect:

    3/8 ÷ 9
    = 3/8 ÷ 9/1
    = 3/8 x 1/9 = 3/72 = 1/24

    The rest are correct

  • Math - ,

    How come the 9 has to ve over the 1 and the 1 isnt over the 9? I thought I had to add the reciprocal so it'd would be 1/9. I'm confused. =/

  • Math - ,

    Why would you ADD the reciprocal if you multiplied in all the other cases to get the correct answers ??

    9 is the same as 9/1
    the reciprocal of 9/1 is 1/9

    so it becomes 3/8 x 1/9 = 3/72 = 1/24
