Frequently Asked Questions

How are fractions added?
To add fractions, find the Least Common Denominator (LCD), convert each fraction to have that denominator, then add the numerators. The result is then simplified by dividing by the Greatest Common Divisor (GCD).
How does fraction multiplication work?
Multiply the numerators together and the denominators together, then simplify. For example, (2/3) × (3/4) = 6/12 = 1/2.
Can I enter negative fractions?
Yes. Enter a negative sign before the numerator or whole number to work with negative fractions and mixed numbers.
