Understanding Fraction Calculations and Simplification

A fraction calculator is an essential tool for students, teachers, and professionals working with fractions in 2026. This comprehensive online calculator handles all fraction operations including addition, subtraction, multiplication, and division, while also serving as a fraction simplifier and converter. Whether you need to add fractions calculator with different denominators or convert between fractions and decimals, our tool provides instant accurate results with detailed step-by-step solutions.

Add and Subtract Fractions Calculator

When you add fractions or subtract fractions with different denominators, finding the least common denominator (LCD) is crucial. Our add fractions calculator automatically identifies the LCD, converts both fractions to equivalent forms, then performs the operation. For example, adding 1/4 and 1/3 requires finding LCD of 12, converting to 3/12 and 4/12, resulting in 7/12. The subtract fractions calculator follows the same process but subtracts numerators instead. This fraction calculator with steps shows complete work for understanding the solution method.

Multiply and Divide Fractions Calculator

The multiply fractions calculator performs simpler operations than addition—multiply numerators together and denominators together, then simplify. For instance, 2/3 × 3/4 equals 6/12, which our fraction reducer calculator simplifies to 1/2. The divide fractions calculator multiplies the first fraction by the reciprocal of the second. Dividing 2/3 by 4/5 becomes 2/3 × 5/4 = 10/12 = 5/6. Our mixed number calculator handles both proper fractions and improper fractions, converting between mixed numbers like 2 1/4 and improper fractions like 9/4 automatically.

Simplify Fractions Calculator

Our fraction simplifier online reduces fractions to lowest terms by finding the greatest common divisor (GCD) and dividing both numerator and denominator. For example, simplifying 12/16 requires finding GCD of 4, then dividing: 12÷4 / 16÷4 = 3/4. This simplify fractions calculator works with any fraction size and shows the GCD used for reduction. The fraction reducer calculator is particularly useful for converting improper fractions to mixed numbers—7/4 becomes 1 3/4, making results easier to visualize and understand.

Fraction Converter Calculator

Convert between fractions, decimals, and percentages effortlessly with our fraction converter calculator. The fraction to decimal calculator divides numerator by denominator—3/4 becomes 0.75. The decimal to fraction calculator converts decimals to simplified fractions—0.75 becomes 3/4. Our fraction to percent calculator multiplies the decimal by 100—3/4 = 0.75 = 75%. This comprehensive tool handles all conversion types including repeating decimals, making it the most versatile fraction calculator online for 2026 mathematics education and professional applications.

Frequently Asked Questions

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, 1/4 + 1/3: LCD is 12, so (3/12) + (4/12) = 7/12. Our add fractions calculator automatically finds the LCD and shows step-by-step work for adding any fractions.
How do you simplify fractions?
Simplify fractions by dividing both the numerator and denominator by their greatest common divisor (GCD). For example, 12/16: GCD is 4, so 12÷4 / 16÷4 = 3/4. Our fraction simplifier online automatically finds the GCD and reduces fractions to lowest terms. Use our fraction reducer calculator to simplify any fraction instantly with detailed steps.
How do I convert a fraction to a decimal?
Convert fractions to decimals by dividing the numerator by the denominator. For example, 3/4 = 3 ÷ 4 = 0.75. Our fraction to decimal calculator handles all conversions including repeating decimals. For mixed numbers like 2 1/2, convert to improper fraction (5/2) first, then divide: 5 ÷ 2 = 2.5.
How do you multiply fractions?
Multiply fractions by multiplying numerators together and denominators together, then simplify. For example, 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2. Our multiply fractions calculator automatically performs multiplication and simplifies the result. For mixed numbers, convert to improper fractions first before multiplying.
What is the difference between proper and improper fractions?
A proper fraction has a numerator smaller than the denominator (like 3/4), representing a value less than 1. An improper fraction has a numerator equal to or greater than the denominator (like 7/4), representing a value equal to or greater than 1. Our improper fraction calculator converts between mixed numbers (1 3/4) and improper fractions (7/4) instantly.
How do I divide fractions?
Divide fractions by multiplying the first fraction by the reciprocal of the second fraction. For example, 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6. The reciprocal flips the numerator and denominator of the second fraction. Our divide fractions calculator shows complete steps including finding the reciprocal and simplifying the final answer.
How do you convert decimals to fractions?
Convert decimals to fractions by placing the decimal number over its place value, then simplify. For 0.75: write as 75/100, then simplify to 3/4. For repeating decimals like 0.333..., recognize common patterns (0.333... = 1/3). Our decimal to fraction calculator handles all decimal types including repeating decimals and converts them to simplified fractions automatically.
What is a mixed number calculator?
A mixed number calculator works with numbers that combine whole numbers and fractions, like 2 1/3. Our calculator handles operations with mixed numbers by converting them to improper fractions, performing the calculation, then converting back to mixed number form. For example, 1 1/2 + 2 3/4 = 3/2 + 11/4 = 17/4 = 4 1/4.
