It is odd that 1 got the smallest number of responses, since it's by far the second best answer.
- gus_massa 4y agoIf you use a bad summation algorithm, 12/13 + 7/9 = (12+7)/(13+9) = 19/22, so 19 will be probably a common answer. I can't imagine how to get 21. Perhaps 12/13 + 7/9 = (12+9)/(17+7) = 21/20 ??? It's somewhat like a bad version of a division, but I don't expect it to be so popular.
