$\frac{5}{11}$
In order to simplify the expression to lowest terms, we need to cancel the common factors. Then, we multiply the numerators by each other and the denominators by each other. $-\frac{7}{9}\times\frac{5}{11}\times-\frac{18}{14}$ =$-\frac{1}{9}\times\frac{5}{11}\times-\frac{18}{2}$ =$-\frac{1}{1}\times\frac{5}{11}\times-\frac{2}{2}$ =$-\frac{1}{1}\times\frac{5}{11}\times-\frac{1}{1}$ =$\frac{-1\times5\times-1}{1\times11\times1}$ =$\frac{5}{11}$
