Practice Multiplying Fractions in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
To multiply fractions, multiply the numerators together and the denominators together: \frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}. Simplify the result by cancelling common factors.
\frac{2}{3} \times \frac{3}{4} means 'two-thirds of three-quarters.' Take \frac{3}{4} of something, then take \frac{2}{3} of that result.
Example 1
easyMultiply \frac{2}{3} \times \frac{5}{7}.
Example 2
mediumCompute \frac{4}{9} \times \frac{3}{8}.
Example 3
easyMultiply \frac{3}{5} \times \frac{2}{9}.
Example 4
mediumA tank is \frac{3}{4} full. If \frac{2}{5} of the water is used, what fraction of the tank is still full?
