You can put this solution on YOUR website!
Since 117/13 = 9, this means that 13*9a = 117a. So multiply top and bottom of the fraction by 9a to get

3%2F13+=+%283%2A9a%29%2F%2813%2A9a%29+=+%2827a%29%2F%28117a%29


So 3%2F13+=+%2827a%29%2F%28117a%29

Let me know if you need more help or if you need me to explain a step in more detail.
