Practice Operations with Rational Numbers in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Extending addition, subtraction, multiplication, and division to the full set of rational numbers—including fractions, decimals, mixed numbers, and their negative counterparts.
Once you can handle integers and fractions separately, combine the skills: apply the sign rules you know from integers to fractions and decimals. -\frac{2}{3} + \frac{1}{4} uses common denominators AND sign rules at the same time.
Example 1
easyCalculate \(\frac{2}{3} + \frac{1}{4}\).
Example 2
mediumCalculate \(\frac{5}{6} \times \frac{3}{10}\) and simplify.
Example 3
easyCalculate \(\frac{3}{4} - \frac{1}{6}\).
Example 4
mediumCalculate \(\frac{7}{8} \div \frac{3}{4}\).
