I love Math so much to the point that I don't need your stupid math problem.

I'm only kidding, I'm just pointing out that I'm lazy and would rather play PS2.

My answer to your problem is, 72, 562, 12 1/2, 352. My question is: How many times can you take 1 nanogram off of a bowl of Marijuana and still wind up with less than a half an ounce?
