How to Subtract Fractions – Step-by-Step Guide

Step 1: Find a Common Denominator

To subtract fractions, both fractions must have the same denominator. Find the least common denominator (LCD) for both fractions.

Step 2: Convert the Fractions

Adjust each fraction so they have the common denominator by multiplying both numerator and denominator by the necessary factor.

Step 3: Subtract the Numerators

Once the denominators are the same, subtract the numerators while keeping the denominator unchanged.

Step 4: Simplify the Fraction

If possible, simplify the resulting fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

Example:

Subtract 3/4 – 1/6

Step 1: Find LCD of 4 and 6, which is 12.

Step 2: Convert fractions: (3×3)/(4×3) = 9/12 and (1×2)/(6×2) = 2/12

Step 3: Subtract: 9/12 – 2/12 = 7/12

Step 4: 7/12 is already in the simplest form.

Final Answer: 7/12
