❓ Frequently Asked Questions
What is a mixed fraction and how do I convert it to an improper fraction?
A mixed fraction has a whole part and a fractional part (e.g., 3 2/5). Convert with (whole × denominator + numerator) / denominator. Example: 3 2/5 = (3×5+2)/5 = 17/5.
How can I convert a mixed fraction to a percentage quickly?
Convert to decimal: whole + (numerator/denominator), then multiply by 100%. Example: 2 1/4 → 2.25; 2.25 × 100% = 225%.
What is a fast method to add or subtract mixed fractions?
Convert to improper fractions, find a common denominator, add/subtract, then simplify. If desired, convert back to a mixed number.
How do you multiply or divide mixed fractions efficiently?
Convert to improper fractions, multiply (or multiply by the reciprocal for division), then simplify. Optionally convert the result back to a mixed number.
