To subtract fractions with the same or different denominators, follow these steps: 1) If the denominators are different, make them the same by finding a common denominator and multiplying the numerators and denominators accordingly. 2) Write the denominator of the fractions. 3) Subtract the numerators. 4) Simplify if possible by dividing both the numerator and denominator by any common factors.
