Formula
The general formula for subtracting fractions is:
a/b – c/d = (a * d – b * c) / (b * d)
Where:
- a = Numerator of the first fraction
- b = Denominator of the first fraction
- c = Numerator of the second fraction
- d = Denominator of the second fraction
This formula allows you to subtract two fractions effectively by converting them to a common denominator.
Example Calculation
Let’s consider an example:
Subtract 3/4 from 5/6.
Using the formula:
- Numerators: 5 (from 5/6) and 3 (from 3/4)
- Denominators: 6 (from 5/6) and 4 (from 3/4)
Step 1: Find a common denominator.
The least common multiple (LCM) of 6 and 4 is 12.
Step 2: Convert both fractions:
- 5/6 = 10/12
- 3/4 = 9/12
Step 3: Now subtract:
10/12 – 9/12 = 1/12
The result is 1/12.
