Subtracting Fractions
Subtracting fractions requires finding a common denominator, converting the fractions, subtracting the numerators, and simplifying the result. This process ensures accurate fraction arithmetic.
Fraction Subtraction Steps
Step 2: Convert fractions to equivalent fractions with LCD
Step 3: Subtract the numerators
Step 4: Keep the common denominator
Step 5: Simplify the result
Example: 3/4 - 1/6 = 9/12 - 2/12 = 7/12
Common Fraction Subtractions
| Subtraction | Common Denominator | Calculation | Result |

Frequently Asked Questions
How do you subtract fractions?
To subtract fractions: 1) Find a common denominator, 2) Convert fractions to equivalent fractions with the common denominator, 3) Subtract the numerators, 4) Keep the common denominator, 5) Simplify if possible.
How do you subtract fractions with different denominators?
Find the least common multiple (LCM) of the denominators to get a common denominator. Convert both fractions to equivalent fractions with this common denominator, then subtract the numerators.
What is a common denominator?
A common denominator is a shared multiple of the denominators of two or more fractions. The least common denominator (LCD) is the smallest positive common multiple of the denominators.
