How do I add fractions with different denominators?

To add fractions with different denominators, first find the least common denominator (LCD), convert each fraction to an equivalent fraction with the LCD, then add the numerators. For example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12. Our calculator handles this automatically.

What's the easiest way to multiply fractions?

Multiplying fractions is straightforward: multiply the numerators together and multiply the denominators together. For example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2. Always simplify the result to its lowest terms.

How do I divide fractions?

To divide fractions, multiply the first fraction by the reciprocal (flipped version) of the second fraction. For example: 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9. Remember the phrase 'keep, change, flip' - keep the first fraction, change division to multiplication, flip the second fraction.

How do I simplify fractions to lowest terms?

To simplify a fraction, divide both the numerator and denominator by their greatest common divisor (GCD). For example: 12/16 can be simplified by dividing both by 4 to get 3/4. Our calculator automatically simplifies all results.

Can I work with mixed numbers in this calculator?

Yes! Mixed numbers (like 2 1/3) can be entered by converting them to improper fractions first, or by using separate inputs if provided. A mixed number is converted to an improper fraction by multiplying the whole number by the denominator, adding the numerator, and placing the result over the original denominator.
