Answer
$\dfrac{64}{11}$.
Work Step by Step
To convert a mixed number to an improper fraction, perform the following steps:
(1) Multiply the numerator to the whole number part.
$11(5) = 55$
(2) Add the numerator to the result in (1).
$55+9 = 64$
(3) Write the result in (2) as numerator and write the denominator (the denominator is the same as that of the mixed number)
$\dfrac{64}{11}$
Thus, the given mixed number is equivalent to $\dfrac{64}{11}$.
