2. Enter your answer as a fraction (any equivalent form is accepted) and press Check.
3. Read the feedback and the step-by-step solution, then press Next.

The method

To add or subtract fractions you rewrite them over a common denominator, combine the numerators, and simplify. The solution panel shows each of those steps and gives the answer in lowest terms.
