Start with 1/2 and add or subtract the fractions along the path, always moving down or to the right. the objective is to obtain a total of 1 after having added the last fraction 1/12.

The common denominator is 24, let's write 24 times the fractions here

12 10 -7 6

8 -9  4  1

-4 6  5  2

There are four simple paths, one for each of our columns.  Their sums are 29, 26, 20, 24

24 means 24/24 or 1, that's the one.  1/2 + 5/12 + -7/24 + 1/4 + 1/24 + 1/12 = 1

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
