Frequently Asked Questions (FAQ)
What is a fraction calculator?
A fraction calculator is a specialized mathematical tool designed to perform operations like addition, subtraction, multiplication, and division on fractions, mixed numbers, and whole numbers with perfect accuracy, avoiding decimal rounding errors.
How do you add or subtract fractions?
To add or subtract fractions, they must have a common denominator. Find the Least Common Multiple (LCM) of the denominators, convert both fractions to have this new denominator, and then add or subtract the numerators while keeping the denominator the same. Our calculator shows this step-by-step.
How do you multiply fractions?
Multiplying fractions is straightforward: simply multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator. Finally, simplify the resulting fraction if possible.
How do you divide fractions?
To divide by a fraction, you use the "keep-change-flip" method. Keep the first fraction the same, change the division sign to a multiplication sign, and flip (find the reciprocal of) the second fraction. Then multiply normally.
How do you simplify a fraction?
To simplify or reduce a fraction, find the Greatest Common Divisor (GCD) of both the numerator and the denominator. Then, divide both numbers by that GCD. For example, for 8/12, the GCD is 4. Dividing both by 4 gives the simplified fraction 2/3.
What is a mixed fraction / mixed number?
A mixed number is a whole number combined with a proper fraction, such as 2 1/2. It represents a value greater than a whole. You can input mixed numbers into our calculator by separating the whole number and fraction with a space.
What is an improper fraction?
An improper fraction is a fraction where the numerator (top number) is equal to or greater than the denominator (bottom number), such as 5/4 or 3/3. They can be converted into mixed numbers or whole numbers.
Can this calculator convert fractions to decimals?
Yes! Every calculation automatically displays the decimal equivalent of the result. You can also use the "Quick Converter" tool provided on this page to instantly convert any specific fraction into a decimal, or decimal into a fraction.
