How how to subtract fractions with different denominators Actually Works
Subtracting fractions with different denominators involves a straightforward yet often misunderstood process. The key lies in finding the least common multiple (LCM) of both denominators. This LCM serves as the new denominator for the resulting fraction. To achieve this, look for the smallest multiple that both original denominators can divide into evenly. Once identified, simply replace the original denominators with the LCM, ensuring that the fractions share a common base for accurate subtraction.
