Find answers to common questions about fraction calculations
To add fractions with different denominators, first find a common denominator (usually the least common multiple of the denominators). Then convert each fraction to an equivalent fraction with the common denominator, add the numerators, and simplify the result if possible.
A simplified fraction is one where the numerator and denominator have no common factors other than 1. For example, 2/4 simplifies to 1/2 because both numerator and denominator can be divided by 2.
To convert an improper fraction (where the numerator is larger than the denominator) to a mixed number, divide the numerator by the denominator. The quotient becomes the whole number part, and the remainder becomes the numerator of the fractional part, with the same denominator.
Yes, our fraction calculator supports negative numbers. You can input negative numerators or denominators, and the calculator will handle them correctly in all operations.
Division by zero is undefined in mathematics. If you enter 0 as a denominator, the calculator will display an error message asking you to enter a valid non-zero denominator.
