Answer:[tex]31 \frac{1}{12} [/tex]Step-by-step explanation:#1 : To add mixed numbers/fractions, we first need to convert them into improper fractions.[tex]17 \frac{3}{4} + 13 \frac{1}{3} = \frac{71}{4} + \frac{40}{3} [/tex]#2 : Then, perform adding the fractions together.[tex] \frac{71}{4} + \frac{40}{3} = \frac{213}{12} + \frac{160}{12} = \frac{373}{12} [/tex]#3 : After that, convert the improper fraction back to a mixed number/fraction.[tex] \frac{373}{12} = 31 \frac{1}{12} [/tex]Since we no longer need to simplify, 31 1/12 is the final answer.
