Haha ok, so this is how I think of it. We have amount of orange juice per person currently, but we want the ratio of orange juice to people to remain the same, since each person will get the same amount of orange juice that way. \[\LARGE \frac{4/5 \ cups }{9 \ People}=\frac{OJ}{10 \ People}\]

But hey, can't we just solve this for the amount of OJ we need?

No - the answer is B
9 servings requires 4/5 cups of orange juice.
10 servings would require you to increase this by a factor of 10/9
So 4/5 * 10/9 = 40/45 = 8/9
The answer is B
