#### Answer

$\dfrac{23}{7}$

#### 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.
$7(3) = 21$
(2) Add the numerator to the result in (1).
$21+2 = 23$
(3) Write the result in (2) as numerator and write the denominator (the denominator is the same as that of the mixed number)
$\dfrac{23}{7}$
Thus, the given mixed number is equivalent to $\dfrac{23}{7}$.
