$9 \frac{7}{8}$

#### Explanation:

$\text{ "11/2 + 1 3/8 + 1 3/4 + 1 1/4" } \leftarrow$ write them in the same form
$\text{ } \downarrow$
$= 5 \frac{1}{2} + 1 \frac{3}{8} + 1 \frac{3}{4} + 1 \frac{1}{4}$

= 8 (?+?+?+?)/8" "larr add whole numbers, find the LCD

$= 8 \frac{4 + 3 + 6 + 2}{8} \text{ } \leftarrow$ make equivalent fractions.

$= 8 \frac{15}{8} \text{ } \leftarrow$ add the numerators

$= 8 + 1 \frac{7}{8}$

$= 9 \frac{7}{8}$
