Answer:

2 $\frac{1}{2}$

Step-by-step explanation:

Change the mixed numbers to improper fractions

( $\frac{9}{2}$ - $\frac{11}{3}$ ) + $\frac{5}{3}$ ← the LCM of 2 and 3 is 6

= $\frac{9(3)}{2(3)}$ - $\frac{11(2)}{3(2)}$ + $\frac{5(2)}{3(2)}$

= $\frac{27}{6}$ - $\frac{22}{6}$ + $\frac{10}{6}$

= $\frac{5}{6}$ + $\frac{10}{6}$

= $\frac{15}{6}$

= $\frac{5}{2}$

= 2 $\frac{1}{2}$
