Introduction
Subtracting fractions follows similar rules to adding them. When denominators are the same, the process is straightforward.
The Subtraction Rule
Subtract the numerators and keep the denominator unchanged.
Example
5/8 - 2/8 = 3/8
Real-World Application
Subtraction helps us find how much is left or the difference between amounts.
Example
If you have 5/6 of a pizza and eat 2/6, you have 3/6 (or 1/2) left.
