Step-by-Step Results
The calculator shows the result in simplified form and the intermediate steps. Reviewing the steps helps you understand and replicate the calculation by hand.
Negative Fractions
Enter a negative numerator for a negative fraction. Division by zero is detected and shown as an error. The denominator is always kept positive in the output.
Frequently Asked Questions
Find a common denominator (the LCM of the two denominators), convert each fraction, then add or subtract the numerators and simplify. For example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.
Multiply the numerators together and the denominators together, then simplify. For example: 2/3 x 3/4 = 6/12 = 1/2.
Dividing by a fraction equals multiplying by its reciprocal. Flip the second fraction, then multiply. For example: 2/3 / 4/5 = 2/3 x 5/4 = 10/12 = 5/6.
A mixed number combines a whole number and a fraction, such as 2 and 1/2. Convert to an improper fraction first: 2 and 1/2 = (2x2+1)/2 = 5/2. This calculator accepts improper fractions directly.
A fraction is fully simplified when numerator and denominator share no common factors other than 1. Divide both by their GCD to simplify. This calculator always returns results in simplest form.
