Calculate Mixing Ratios
Substances
Formulas Used
Percentage: (Substance Amount ÷ Total Amount) × 100
Ratio: Substance Amount ÷ Total Amount
Scaled Amount: Original Amount × Scale Factor
Scale Factor: Target Total ÷ Original Total
Example Calculation
Paint Mixing Example
Goal: Mix blue and yellow paint to make green
Recipe: 2 parts blue + 3 parts yellow = 5 parts total
Desired amount: 100 mL of green paint
Step-by-Step Solution
1. Total parts = 2 + 3 = 5 parts
2. Blue percentage = (2 ÷ 5) × 100 = 40%
3. Yellow percentage = (3 ÷ 5) × 100 = 60%
4. Blue amount = 100 mL × 40% = 40 mL
5. Yellow amount = 100 mL × 60% = 60 mL
Result: Mix 40 mL blue + 60 mL yellow = 100 mL green

Mixing Tips
All substances must use the same unit
Percentages always sum to 100%
Use scale factor to adjust total amount
Ratios remain constant when scaling
Mix in order of largest to smallest
Understanding Mixing Ratios
What are Mixing Ratios?
A mixing ratio represents the proportion of each component in a mixture relative to the total amount. It can be expressed as percentages, decimal ratios, or simplified whole number ratios (like 2:1 or 3:2:1).
Applications
- •Paint and color mixing
- •Chemical solution preparation
- •Food and beverage recipes
- •Construction material mixing
- •Fuel and oil blends
Key Formulas
Percentage = (Amount ÷ Total) × 100
Ratio = Amount₁ : Amount₂ : Amount₃
Scale Factor = New Total ÷ Original Total
Scaling Methods
- Multiplier: Scale all amounts by a fixed factor
- Target Total: Calculate amounts for a specific total
- Proportional: Maintain original ratios while scaling
Remember: The ratio between components stays constant regardless of the total amount.
