Frequently asked questions
How do I add two fractions?
Find a common denominator, convert both fractions, then add the numerators. 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
How do I divide fractions?
Multiply the first fraction by the reciprocal (flip) of the second. 1/2 ÷ 1/3 = 1/2 × 3/1 = 3/2.
How do I convert a fraction to a decimal?
Divide the numerator by the denominator. 3/4 becomes 3 ÷ 4 = 0.75. This calculator's fraction operations return a simplified fraction, which you can convert to a decimal the same way afterward.
How do I just simplify one fraction, without a second one?
Set the second fraction to 1/1 and choose "×" (multiply) - multiplying by 1/1 doesn't change the value, so the result shown is your original fraction reduced to its simplest form.
How do I subtract fractions with different denominators?
Find a common denominator first, convert each fraction to that denominator, then subtract the numerators. For 3/4 - 1/6, the common denominator is 12: 9/12 - 2/12 = 7/12. This calculator handles the common-denominator step automatically.
