Fraction Calculator

Find the least common denominator (LCD), convert both fractions to equivalent fractions with the LCD, then add the numerators and keep the denominator.

Multiply the numerators together and the denominators together: (a/b) × (c/d) = (a×c)/(b×d). Then simplify if possible.

Multiply the whole number by the denominator, add the numerator, and put the result over the original denominator. Example: 2⅓ = (2×3+1)/3 = 7/3.
