Sorry, but you are going to have to repost this problem using sufficient parentheses so that it is clear which are the numerators and denominators in which fractions. Since you didn't use any parentheses, there are simply too many ways to interpret what you wrote.

Without parentheses your problem reads as:
3+-v%2Fv+-8+-9v+-7%2F8+-v
If this is correct (which I doubt), then keep reading. If not, please repost this question putting parentheses around each numerator and each denominator.

Since v/v = 1 we can simplify this to:
3+-+1+-+8+-9v+-7%2F8+-v
Rewriting as additions we get:
3+%2B+%28-1%29+%2B+%28-8%29+%2B+%28-9v%29+%2B+%28-7%2F8%29+%2B+%28-v%29
Rearranging we get:
3+%2B+%28-1%29+%2B+%28-8%29+%2B+%28-7%2F8%29+%2B+%28-9v%29+%2B+%28-v%29
Combining the integer and variable terms we get:
-6+%2B+%28-7%2F8%29+%2B+%28-10v%29
Adding the integer and the fraction we get:
-6%267%2F8+%2B+%28-10v%29
