🍪 Part 1: Understanding Recipe Ratios

1. What does a ratio represent in a recipe? Circle the best answer:

The total amount of ingredients needed

The proportional relationship between ingredients

The cooking time required

The temperature needed for cooking

2. A recipe serves 4 people and uses 2 cups of flour. What is the ratio of flour to servings?

3. If you want to make the same recipe for 6 people, what multiplication factor would you use?

📏 Part 2: Metric Measurement Conversions

4. Convert these measurements. Fill in the blanks:

a) 1500 mL = _______ L

b) 2.5 kg = _______ g

c) 750 g = _______ kg

d) 0.25 L = _______ mL

5. Which metric units are most appropriate for measuring these ingredients? Match each ingredient to its best unit:

1. Salt

2. Milk

3. Flour

4. Vanilla essence

A. Litres (L)

B. Grams (g)

C. Millilitres (mL)

D. Kilograms (kg)

🧮 Part 3: Recipe Scaling Calculations

Original Chocolate Chip Biscuit Recipe (Serves 4 people):

• 300g plain flour
• 150g butter
• 100g brown sugar
• 2 eggs
• 200g chocolate chips
• 5mL vanilla essence

6. Scale this recipe to serve 6 people. Show your working:

New Recipe for 6 people:

• Plain flour: _______ g
• Butter: _______ g
• Brown sugar: _______ g
• Eggs: _______
• Chocolate chips: _______ g
• Vanilla essence: _______ mL

7. Now scale the original recipe to serve 10 people. Show your working:

New Recipe for 10 people:

• Plain flour: _______ g
• Butter: _______ g
• Brown sugar: _______ g
• Eggs: _______
• Chocolate chips: _______ g
• Vanilla essence: _______ mL

🤔 Part 4: Problem Solving and Reasoning

8. A recipe for 8 servings calls for 3 eggs. How many eggs would you need for 12 servings? Show your calculation:

9. What might happen if you don't maintain the correct ratios when scaling a recipe? Check all that apply:

The texture might change (too dry or too wet)

The flavour balance could be affected

The recipe might not work at all

Nothing would change

10. A recipe serves 6 people and uses 450g of flour. You only have 300g of flour available. How many people can you serve with the ingredients you have? Explain your reasoning:

🎯 Part 5: Real-World Application

11. Create your own scaling problem: Write down a simple recipe for 4 people, then scale it for a different number of servings. Show all your working:

My Original Recipe (serves 4):

Scaled Recipe (serves _____):

12. Reflection: Why is understanding ratios important in cooking and in everyday life?
