Frequently Asked Questions
How do I simplify a fraction?
To simplify a fraction, divide both the numerator and denominator by their Greatest Common Divisor (GCD). For 12/16: GCD(12,16) = 4, so 12÷4 = 3 and 16÷4 = 4 → simplified to 3/4. Our simplifier finds the GCD automatically and shows the step-by-step simplification process.
When is a fraction fully simplified?
A fraction is fully simplified (in lowest terms) when the GCD of the numerator and denominator equals 1. For example, 7/13 is already simplified since GCD(7,13) = 1. The fraction 6/9 is not simplified because GCD(6,9) = 3, giving 2/3 as the fully simplified form.
What is the difference between a proper and improper fraction?
A proper fraction has a numerator smaller than the denominator (e.g., 3/4). An improper fraction has a numerator equal to or greater than the denominator (e.g., 7/4). Improper fractions can be converted to mixed numbers: 7/4 = 1¾. Both can be simplified the same way using GCD.
