In mathematics, a fraction represents a part of a whole and is expressed with a numerator and a denominator. The numerator indicates the number of parts you have, while the denominator indicates the total number of equal parts that make up the whole. For instance, in the fraction 3/8, 3 is the numerator, and 8 is the denominator. Imagine a pie cut into 8 equal slices. If you have 3 of those slices, you have 3/8 of the pie. The denominator cannot be zero, as this would make the fraction undefined. Fractions can be used in various mathematical operations, as outlined below.

Fraction Addition
Adding fractions requires a common denominator. One reliable method to find a common denominator is by multiplying the denominators of all fractions involved. While this method always works, it may not always yield the least common denominator.
The formula for adding two fractions is:
a/b + c/d = (a×d)/(b×d) + (c×b)/(d×b) = (ad + bc)/(bd)Example:
3/4 + 1/6 = (3×6)/(4×6) + (1×4)/(6×4) = 18/24 + 4/24 = 22/24 = 11/12For multiple fractions, extend this process by multiplying each numerator and denominator by the product of the denominators of the other fractions.
Example with three fractions:
1/4 + 1/6 + 1/2 = (1×6×2)/(4×6×2) + (1×4×2)/(6×4×2) + (1×4×6)/(2×4×6) = 12/48 + 8/48 + 24/48 = 44/48 = 11/12A more efficient approach to find a common denominator is to use the Least Common Multiple (LCM) of the denominators. This often results in smaller numbers and a simplified fraction faster.
Example using LCM: For 1/4 + 1/6 + 1/2, the LCM of 4, 6, and 2 is 12.
| Multiples of 2: | 2, 4, 6, 8, 10, 12 |
|---|---|
| Multiples of 4: | 4, 8, 12 |
| Multiples of 6: | 6, 12 |
Convert each fraction to have a denominator of 12:
1/4 = (1×3)/(4×3) = 3/12
1/6 = (1×2)/(6×2) = 2/12
1/2 = (1×6)/(2×6) = 6/12Now add the numerators:
3/12 + 2/12 + 6/12 = (3+2+6)/12 = 11/12Fraction Subtraction
Subtracting fractions is similar to addition, requiring a common denominator.
The formula for subtracting two fractions is:
a/b – c/d = (a×d)/(b×d) – (c×b)/(d×b) = (ad – bc)/(bd)Example:
3/4 – 1/6 = (3×6)/(4×6) – (1×4)/(6×4) = 18/24 – 4/24 = 14/24 = 7/12Fraction Multiplication
Multiplying fractions is straightforward and does not require a common denominator. Multiply the numerators together and the denominators together.
The formula is:
a/b × c/d = (a×c)/(b×d) = ac/bdExample:
3/4 × 1/6 = (3×1)/(4×6) = 3/24 = 1/8Fraction Division
Dividing fractions involves multiplying the first fraction by the reciprocal of the second fraction. The reciprocal is obtained by swapping the numerator and denominator of the second fraction.
The formula is:
(a/b) / (c/d) = (a/b) × (d/c) = (a×d)/(b×c) = ad/bcExample:
(3/4) / (1/6) = (3/4) × (6/1) = (3×6)/(4×1) = 18/4 = 9/2Fraction Simplification
Simplifying fractions means reducing them to their lowest terms. This is done by dividing both the numerator and the denominator by their Greatest Common Factor (GCF). Our fraction calculator online automatically simplifies results.
Converting Between Fractions and Decimals
Decimal to Fraction: To convert a decimal to a fraction, recognize that each decimal place represents a power of 10. For example, the first decimal place is tenths (10-1), the second is hundredths (10-2), and so on.
For 0.1234, the last digit is in the fourth decimal place (10-4 or 10,000). Use 10,000 as the denominator and the decimal digits as the numerator: 1234/10000. Then, simplify the fraction by finding the GCF of 1234 and 10000, which is 2. Simplified fraction: 617/5000.
Fraction to Decimal: For fractions with denominators that are powers of 10 (or easily converted), conversion is simple. For example, 1/2 can be converted to 5/10, which is 0.5. For other fractions, perform long division of the numerator by the denominator.
