In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
So your answer would be any fractions between the two.
First you convert the fractions to 8/24 and 12/24 so they would hae the same denominator.
Then find the fractions in between:
9/24
10/24
11/24
Those three are your answer. :))
