Find the least common multiple of 8 and 11.

\( \begin{array}{lllll}\text { (f) } 4 \frac{1}{2}+3 \frac{4}{5} & \text { (g) } 6 \frac{2}{3}+4 \frac{8}{9} & \text { (h) } 4 \frac{5}{6}+3 \frac{1}{3} & \text { (i) } 4 \frac{3}{8}+6 \frac{3}{4} & \text { (j) } 6 \frac{1}{2}+4 \frac{3}{10} \\ \text { (k) } 2 \frac{5}{9}+3 \frac{2}{3} & \text { (l) } 6 \frac{7}{10}+4 \frac{3}{5} & \text { (m) } 4 \frac{11}{12}+2 \frac{2}{3} & \text { (n) } 5 \frac{7}{9}+2 \frac{2}{3} & \text { (o) } 2 \frac{4}{5}+4 \frac{7}{10} \\ \text { (p) } 2 \frac{1}{4}+2 \frac{1}{5} & \text { (q) } 5 \frac{1}{2}+3 \frac{4}{7} & \text { (r) } 6 \frac{2}{3}+4 \frac{3}{5} & \text { (s) } 3 \frac{3}{4}+4 \frac{4}{5} & \text { (t) } 7 \frac{3}{8}+4 \frac{1}{3}\end{array} \)

How many inches are in 8 yards?

\( ( 4 x + 6 ) ^ { \circ } / ( 6 x + 14 ) ^ { \circ } \)

7. \( -8-(-6) \)

Which of the following is a value of \( x \) for which the expression \( \frac{-3}{x^{2}+3 x-12} \) is undefined?
