Answer:

Explanation:
I figured this out by knowing that 1/3 is equal to .3 repeating. So all I had to figure out is what times 3 would equal to 6 wholes. I kept plugging in numbers more than 12* to find 6.3 repeating.
*I said more than 12 because we know that 12/3 equals 4, so it had to be more than that.
