Common Ratio Calculator Mistakes to Avoid

• Reversing Antecedent and Consequent Terms: Swapping the order of comparison ($A:B \neq B:A$). For example, a $2:3$ ratio is not equal to a $3:2$ ratio.
• Adding Ratios Directly Without Total Parts: Adding terms across ratios directly without converting them to fractions of a shared total ($A / (A+B)$).
• Inconsistent Unit Comparisons: Comparing quantities in different units (e.g., comparing $500\text{ g}$ to $2\text{ kg}$ as $500:2$ instead of converting to $500:2000 = 1:4$).
• Multi-Part Scaling Errors: Scaling two-part ratios ($A:B$) to three-part ratios ($A:B:C$) without establishing a common linking term.
• Simplifying Fractional Ratios Incorrectly: Inverting terms when clearing fractions in ratios (e.g., $\frac{1}{2} : \frac{1}{3} = 3:2$, not $2:3$).
• Confusing Ratio ($A:B$) with Proportion Fraction ($\frac{A}{A+B}$): Treating ratio comparison between parts as a fraction of the whole.
