Adding and subtracting fractions with different bottoms (called denominators) can be tricky. The steps might feel overwhelming, and it's easy to make mistakes. Here are some strategies to help you out:
Finding a Common Denominator: This is often the hardest part. You need to find a number that both denominators can turn into. This number is called the least common multiple (LCM), and finding it can be confusing.
Adjusting Fractions: Once you have that common denominator, you'll have to change each fraction. This means you multiply each fraction by a version of 1 that fits. It sounds tricky, but it’s just a way to keep the value the same.
Doing the Math: After you've made those changes, add or subtract the tops (numerators) while keeping the common denominator the same.
Simplifying: Finally, you need to simplify your answer. This step can be tough if the fractions are complicated.
With practice and careful attention, you can get better at this!
