Here, we want to select which of the fractions are rational

To get this, we need to understand what rational numbers are

Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero

From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero

This means all the given fractions are rational

Answer:
9.1

Explanation:
Use the distance formula
d=sqrt[(x2-x1)^2 + (y2-y1)^2]
d=sqrt[(3-12)^2 + (4-5)^2]
d=sqrt[(-9)^2 + (-1)^2]
d=sqrt[81 + 1]
d=sqrt[82]
d=9.055≈9.1

Where (x1, y1) is (12,5) and (x2, y2) is (3, 4)
