How to Simplify a Fraction
Find the GCF of the numerator and denominator, then divide both by it. Example: 6/8 → GCF(6,8) = 2 → 3/4.
How to Add Fractions with Different Denominators
Find the LCD of both denominators, convert each fraction to an equivalent fraction with the LCD, then add the numerators. Example: 1/2 + 1/3 → LCD = 6 → 3/6 + 2/6 = 5/6.
How to Divide Fractions
Multiply the first fraction by the reciprocal (flipped) of the second. Example: 5/6 ÷ 2/3 = 5/6 × 3/2 = 15/12 = 5/4.
