Formula:
To subtract fractions, you generally follow these steps:
- Convert Mixed Numbers: If you have mixed numbers (e.g., 1 1/2), convert them to improper fractions.
- Find Common Denominator: Find the Least Common Multiple (LCM) of the denominators, or simply multiply them for a common denominator.
- Adjust Numerators: Rewrite both fractions with the common denominator.
- Subtract Numerators: Subtract the second numerator from the first.
- Simplify: Simplify the resulting fraction to its lowest terms.
For example, to subtract a/b from c/d:
(c/d) - (a/b) = (c × b - a × d) / (d × b)
Where:
- a, c are numerators
- b, d are denominators
