Miscalculating values: Always double-check your math! A small mistake can mess everything up.
Ignoring negative signs: Pay attention to negative numbers; they can change your answer in surprising ways.
Forgetting to simplify: After you find a value, remember to simplify your fractions or answers.
Setting up the proportion wrong: Make sure your ratios are set up correctly before you start cross-multiplying.
