Difference X & Z----> 1/8 - 1/12 = 3/24 - 2/24 = 1/24
Difference X & Y----> 1/24 รท 2 = 1/24 x 1/2 = 1/48
Value of Y ------------> 1/12 + 1/48 = 4/48 + 1/48 = 5/48 (answer)

Whenever you need to find a mid-value, just add the two ends and divide the result by 2.

So, (1/12) + (1/8) = 5/24
Now, divide that by 2, you get 5/48 Smile
