Understanding Fractions

What is a Fraction?

A fraction represents a part of a whole, expressed as a ratio of two integers: the numerator (top number) and the denominator (bottom number). For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator, representing three parts out of four equal parts.

Fraction Operations

Addition: To add fractions, find a common denominator, convert both fractions, then add the numerators. Example: 1/4 + 1/3 = 3/12 + 4/12 = 7/12
Subtraction: Similar to addition, find a common denominator, convert both fractions, then subtract the numerators. Example: 3/4 - 1/2 = 3/4 - 2/4 = 1/4
Multiplication: Multiply the numerators together and the denominators together. Example: 2/3 × 3/4 = 6/12 = 1/2 (simplified)
Division: Multiply the first fraction by the reciprocal of the second fraction. Example: 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9

Mixed Numbers Explained

A mixed number combines a whole number and a fraction, such as 2 3/4. It represents 2 whole units plus 3/4 of another unit. Mixed numbers can be converted to improper fractions (where the numerator is larger than the denominator) for easier calculation. For example, 2 3/4 = 11/4.

Simplifying Fractions

Simplifying a fraction means reducing it to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD). For example, 21/98 simplifies to 3/14 because both 21 and 98 are divisible by 7.

Fraction and Decimal Conversion

Converting between fractions and decimals is straightforward: divide the numerator by the denominator to get a decimal (e.g., 3/4 = 0.75). To convert a decimal to a fraction, express it as a fraction over a power of 10 and simplify (e.g., 0.375 = 375/1000 = 3/8).

Frequently Asked Questions

How do I add fractions with different denominators?

Find the least common denominator (LCD), convert both fractions to equivalent fractions with the LCD, then add the numerators. Our calculator does this automatically for you.

What is an improper fraction?

An improper fraction is one where the numerator is greater than or equal to the denominator, such as 7/4. It can be converted to a mixed number (1 3/4) for easier interpretation.

How do I simplify a fraction?

Divide both the numerator and denominator by their greatest common divisor (GCD). For example, 12/16 simplifies to 3/4 by dividing both by 4.

Can I use this calculator for mixed numbers?

Yes! Our calculator has a dedicated mixed numbers section where you can input values like '2 3/4' and perform all arithmetic operations.

How accurate is the decimal conversion?

Our calculator provides decimal results up to 10 decimal places for maximum precision. Repeating decimals are shown with sufficient digits to identify the pattern.

What's the difference between proper and improper fractions?

A proper fraction has a numerator smaller than the denominator (e.g., 3/4), while an improper fraction has a numerator greater than or equal to the denominator (e.g., 7/4). Improper fractions can be converted to mixed numbers.
