  1. This was a pretty tough problem. Had my class stumped. I eventually came up with 5 and 6/3 + 4 and 8/2 = 9 and 7/1. 9 and 7/1 = 16.

    Thanks for the problem.

    • Just realized my mistake after looking over my work. 6/3 is only 2, which would result in a total of 15 not 16. Back to the drawing board.

  2. My students found this:

    2 4/8 + 7 1/3 = 9 5/6
