Add, subtract, multiply, divide, and simplify fractions including mixed numbers.
A fraction represents a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number). For example, in the fraction 3/4, the numerator is 3 and the denominator is 4, meaning 3 parts out of 4 equal parts.
A mixed number combines a whole number and a fraction, like 2½. To work with mixed numbers in calculations, they are first converted to improper fractions. For example, 2½ becomes 5/2 — calculated as (2 × 2) + 1 = 5 over 2.
To add fractions, find the least common denominator (LCD), convert each fraction, then add the numerators. For example: 1/3 + 1/4 — the LCD is 12, so it becomes 4/12 + 3/12 = 7/12.
Divide both the numerator and denominator by their greatest common divisor (GCD). For example, 8/12 — the GCD is 4, so 8/12 = 2/3.
An improper fraction is one where the numerator is greater than or equal to the denominator, like 7/4. It can be converted to a mixed number: 7/4 = 1¾.
Yes — enter a negative whole number or a negative numerator to work with negative fractions.
