Frequently Asked Questions
How do you add fractions?
Find the Least Common Denominator (LCD). Convert each fraction to an equivalent fraction with the LCD. Add the numerators. Simplify by dividing by the GCD. Example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
How do you multiply fractions?
Multiply the numerators together and the denominators together, then simplify. Example: 2/3 x 3/4 = 6/12 = 1/2.
How do you divide fractions?
Multiply the first fraction by the reciprocal of the second. Example: 2/3 divided by 4/5 = 2/3 x 5/4 = 10/12 = 5/6.
What is a mixed number?
A mixed number combines a whole number and a fraction, like 2 and 1/2. Toggle Mixed number mode in this calculator to enter mixed numbers.
How do you simplify a fraction?
Divide both the numerator and denominator by their Greatest Common Divisor (GCD). Example: 6/8 with GCD of 2 simplifies to 3/4.
