Add, subtract, multiply and divide fractions and mixed numbers, with results automatically simplified.
a/b + c/d = (ad + cb) / bd
1/2 + 3/8: common denominator is 8, giving 4/8 + 3/8 = 7/8 (0.875 as a decimal).
Type mixed numbers with a space between the whole part and the fraction, for example 2 1/4. Improper fractions like 9/4 are accepted too and will be simplified in the answer.
Addition and subtraction need a common denominator; multiplication multiplies straight across; division flips the second fraction and multiplies. Every answer is reduced to lowest terms using the greatest common divisor.
Fractions express parts of equally-sized wholes. You can only add pieces directly when the pieces are the same size, so denominators must match before combining numerators.
An improper fraction has a numerator larger than its denominator, such as 9/4. It equals 2 1/4 as a mixed number.
