D is the correct equation for this problem.
If you were trying to simplify it, it's not posible because 23 is a composite number so I just went ahead and did division for you:
23/46=0.5
I hope this helped!
2/15 = 0.1333333333...
It is a repeating decimal, because a terminarog decimal ends, and this doesn't end.
