The numbers are 5 and 12
(20) and (negative 3)

The factor pairs of 60 are: 60 x 1 30 x 2 20 x 3 15 x 4 12 x 5 10 x 6
-56
12 and -5.
That is it - 17 does not divide in to 60 so it is 17/60 still
60 - 17 = 43
The factor pairs of 36 are (36,1)(18,2)(12,3)(9,4) Even considering their negative counterparts, none of them adds up to -60.
(17 + 60) / 2 = 38.5
