Fraction Simplifier

Find the LCM of the denominators (the lowest common denominator). Convert each fraction to an equivalent fraction with the LCD as denominator. Then add the numerators. For example, 1/4 + 1/6: LCD = 12, so 3/12 + 2/12 = 5/12.

An improper fraction has a numerator larger than the denominator (e.g. 7/4). It represents a value greater than 1 and can be converted to a mixed number: 7/4 = 1¾. Both forms are valid — improper fractions are often easier to multiply and divide.

A fraction is in simplest form (lowest terms) when the GCD of the numerator and denominator is 1 — they share no common factors. For example, 3/4 is in simplest form because GCD(3,4) = 1. But 6/8 is not — GCD(6,8) = 2, so it simplifies to 3/4.
