When to use it

Use it whenever you see a fraction divided by a fraction, reminding you to rewrite the problem as multiplication before simplifying.

Example

$\frac{3}{4} \div \frac{2}{5}$ becomes $\frac{3}{4} \times \frac{5}{2} = \frac{15}{8}$.

Common mistake

Flipping the first fraction instead of the second. You keep the first fraction exactly as it is and only flip the divisor.
