Is 8 over 23 rational?
8/23 is a rational number because all fractions and integers are rational numbers
Is one half a integer?
No, one half which is 1/2 is not a integer. Its a rational number.
Is there a smallest positive rational number?
1/infinity? * * * * * Nice idea but unfortunately that is not a rational number, which is defined as the ration of two integers, x/y where y > 0. Since infinity is not an integer, the suggested ratio is not a rational number. The correct answer is that there is no such number. If any number laid claim to being the smallest positive rational, then half of that number would have a better claim. And then a half of THAT number would be a positive rational that was smaller still. And so on.
