Here is your equation:

\frac{9}{11} \div \frac{5}{11} = a \frac{b}{c}

When you're going to be dividing fractions, you have to keep, change, and flip.

Keep\ \frac{9}{11} \\ Change\ \div\ to\ \times \\ Flip\ \frac{5}{11} = \frac{11}{5}

Your new equation is:

\frac{9}{11} \times \frac{11}{5}

Multiply:

\frac{9}{11} \times \frac{11}{5} = \frac{99}{55} = 1  \frac{44}{55} \rightarrow  1 \frac{4}{5}

Your answer is:

1 \frac{4}{5} \\ a = 1 \\ b = 4 \\ c = 5
