Multiply top and bottom by i to get

9%2F%287i%29+=+%289i%29%2F%287i%2Ai%29

9%2F%287i%29+=+%289i%29%2F%287i%5E2%29

9%2F%287i%29+=+%289i%29%2F%287%28-1%29%29

9%2F%287i%29+=+-%289%2F7%29i

9%2F%287i%29+=+0+%2B+%28-%289%2F7%29%29i

Answer is 9%2F%287i%29+=+0+%2B+%28-%289%2F7%29%29i

Notice how 0+%2B+%28-%289%2F7%29%29i is in the form a%2Bbi where a=0 and b+=+-9%2F7
