FAQ

Frequently Asked Questions

How do you add or subtract fractions with different denominators?

Find the least common multiple (LCM) of the denominators to create equivalent fractions with a shared denominator, then add or subtract the numerators.

How does fraction division work?

To divide fractions, multiply the first fraction by the reciprocal (inverted value) of the second fraction: (a/b) ÷ (c/d) = (a/b) × (d/c).

What is an improper fraction versus a mixed number?

An improper fraction has a numerator greater than or equal to its denominator (e.g., 7/4). A mixed number expresses it as a whole number plus a proper fraction (e.g., 1 3/4).

Can this tool reduce complex fractions to simplest terms?

Yes. The calculator computes the Greatest Common Divisor (GCD) of the numerator and denominator and reduces the fraction automatically.

Is zero allowed in fraction denominators?

No. Division by zero is mathematically undefined, so denominators must be non-zero numbers.
