Frequently asked questions
What is the LCM (Lowest Common Multiple)?
The LCM is the smallest number that both denominators divide into evenly. When adding or subtracting fractions, both fractions must share the same denominator, so you convert them to an equivalent fraction with the LCM as the denominator.
How is fraction division done?
To divide by a fraction, you multiply by its reciprocal. For example, ½ ÷ ¾ = ½ × 4/3 = 4/6 = ⅔.
What is a mixed number?
A mixed number contains both a whole number and a fraction, like 2½. Enter the whole number separately — the calculator combines it with the fraction before computing.
