Frequently Asked Questions (FAQ)

How do I add fractions with different denominators?

Steps: 1) Find the Least Common Denominator (LCD), 2) Convert each fraction to equivalent fractions with the LCD, 3) Add numerators, 4) Simplify. Example: 1/4 + 1/6. LCD = 12. Convert: 3/12 + 2/12 = 5/12. Our calculator shows all these steps automatically.

What's the difference between proper and improper fractions?

Proper fractions: Numerator < Denominator (e.g., 3/4). Improper fractions: Numerator ≥ Denominator (e.g., 5/4). Mixed numbers: Combine whole number and proper fraction (e.g., 1¼). Our calculator handles all three formats and converts between them automatically.

How do I simplify fractions to lowest terms?

Divide both numerator and denominator by their Greatest Common Divisor (GCD). Example: Simplify 18/24. GCD of 18 and 24 is 6. 18÷6 = 3, 24÷6 = 4. Simplified fraction = 3/4. Our calculator finds the GCD automatically and shows the simplification process step-by-step.

How do I convert fractions to decimals and percentages?

To decimal: Divide numerator by denominator (3/4 = 3 ÷ 4 = 0.75). To percentage: Convert to decimal then multiply by 100 (3/4 = 0.75 = 75%). To fraction from decimal: Write decimal as fraction over 10, 100, 1000, etc., then simplify (0.625 = 625/1000 = 5/8). Our calculator provides all conversions automatically.
