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.
Frequently Asked Questions
What is 3/6 simplified?
3/6 simplified is 1/2. GCF(3, 6) = 3, so divide both by 3: 3÷3 / 6÷3 = 1/2.
What is 1/2 + 1/4?
1/2 + 1/4 = 3/4. The LCD of 2 and 4 is 4. Convert 1/2 to 2/4, then add: 2/4 + 1/4 = 3/4.
How do you multiply fractions?
Multiply numerators together and denominators together, then simplify. Example: 2/3 × 3/4 = 6/12 = 1/2.
