It is 90000099999 so yeah that’s how you get how many you need 45 +689/3748 = and you end up with and you end up getting 78473862717 out of 744738 that makes 837 by subtracting, and if you multiple it that will help you get your ratio that goes over the whole problem of the main question and that will be 9 out of 45 so yeah your welcome!
Well, I'm kind of torn between A and B, but I would have to go with B. Hope this helps!
