Question:
By what number should $\frac{-33}{16}$ be divided to get $\frac{-11}{4} ?$
Solution:
Let the number be $\mathrm{x}$.
$\therefore \frac{-33}{16} \div \mathrm{x}=\frac{-11}{4}$
Or $\frac{-33}{16} \times \frac{1}{\mathrm{x}}=\frac{-11}{4}$
or $\frac{1}{\mathrm{x}}=\frac{-11}{4} \times \frac{16}{-33}$
or $\frac{1}{\mathrm{x}}=\frac{4}{3}$
or $\mathrm{x}=\frac{3}{4}$
Thus, the number is $\frac{3}{4}$.
