There is no "the" rational" number since there is an infinity of them. Start with the number halfway between the two: (1/10+1/11)/2 = 21/220. Then try halfway between 1/10 and 21/220, and then halfway between 1/10 and that on. And so on.
The answer is 7.
10

Unless you're a very indecisive personality, the ease or difficulty of picking a number shouldn't have anything to do with what size group of numbers you're asked to pick it out of. But if you're trying to guess what number somebody else is thinking of, then your chance of guessing his number between 1 - 5 correctly is double the chance of guessing his number between 1 - 10 correctly. Between 1 - 5: Your chance of guessing his number is 20%, or 4 to 1 odds against. Between 1 - 10: Your chance of guessing his number is 10%, or 9 to 1 odds against.
