#### Answer

$\dfrac{13}{4}$

#### Work Step by Step

RECALL: To change the mixed number $a\dfrac{b}{c}$ to an improper fraction, perform the following steps: (1) Multiply the denominator to the whole number part then add the numerator to the result. (2) Write the result in Step (1) above as the numerator of the fraction and retain or copy the denominator of the mixed number. Thus, $3\dfrac{1}{4} = \dfrac{4(3)+1}{4} = \dfrac{13}{4}$
