Frequently Asked Questions
What is a fraction and why is it important in mathematics?
A fraction represents a part of a whole, consisting of a numerator (top number) and denominator (bottom number). Fractions are essential for representing values between whole numbers, ratios, percentages, and many real-world applications like cooking, construction, and scientific calculations.
How do I add fractions with different denominators?
To add fractions with different denominators, find the least common multiple (LCM) of the denominators, convert each fraction to have the common denominator, then add the numerators. Our calculator automatically handles this process and simplifies the result.
What is 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 equal to or larger than the denominator (e.g., 5/4). Improper fractions can be converted to mixed numbers for easier understanding.
How do I convert a decimal to a fraction?
To convert a decimal to a fraction, write the decimal as a fraction with the decimal places as the denominator (e.g., 0.75 = 75/100), then simplify by finding the greatest common divisor (GCD) of the numerator and denominator.
Can I use this calculator for mixed numbers?
Yes! Our calculator automatically converts mixed numbers to improper fractions for calculations and provides the result in both improper fraction and mixed number form. Simply enter the whole number, numerator, and denominator.
