Working with fractions
- Add / subtract: use a common denominator, then combine the numerators.
- Multiply: multiply numerators together and denominators together.
- Divide: multiply the first fraction by the reciprocal of the second.
Every result is reduced using the greatest common divisor so it appears in its simplest form.
Frequently asked questions
How do I add fractions?
Give the fractions a common denominator, add the numerators, then simplify. The calculator does this automatically and reduces the answer to lowest terms.
How do I multiply and divide fractions?
To multiply, multiply the numerators and the denominators. To divide, multiply by the reciprocal of the second fraction (flip it). The result is then simplified.
Does it simplify the answer?
Yes. The result is reduced to lowest terms using the greatest common divisor, and the decimal value is shown too.
