When can we add or subtract fractions ?
The addition of fractions teaches us to add two or more fractions with the same or different denominators. The addition of fraction depends on two major conditions:
Subtraction of fractions also follows the same rule as addition of fractions.
If the denominators are the same for given fractions, then we can directly subtract the numerator, keeping the denominator same.
If the denominators of fractions are different, we need to rationalise them first and then perform subtraction.
