Fraction Subtraction Formula

Formula
$$\frac{a}{b} – \frac{c}{d} = \frac{a \cdot d – c \cdot b}{b \cdot d}$$

Explanation:
To subtract two fractions with different denominators, find a common denominator by multiplying both denominators, adjust the numerators accordingly, perform the subtraction, and simplify the result.

Fraction Subtraction – Calculation Example

Subtract: 3/41/6

Step 1: Find common denominator: 4 Γ— 6 = 24
Step 2: Adjust numerators: (3 Γ— 6) = 18, (1 Γ— 4) = 4
Step 3: Subtract: 18 – 4 = 14
Step 4: Result = 14/24
Step 5: Simplify: 14/24 = 7/12

Result: 7/12
