Advent Day 11: Fractions in Festive Baking.

Fractions in Festive Baking. Scaling Recipes Up and Down

Christmas baking often involves changing recipe quantities.

Today’s Skill that Counts, we'll show how to scale ingredients using fractions.

Your recipe needs:

150 g flour

100 g sugar

50 g butter

You want to make one and a half times the recipe.

Step 1: 

Multiply each ingredient by the fraction

Flour: 150 × 1.5 = 225 g

Sugar: 100 × 1.5 = 150 g

Butter: 50 × 1.5 = 75 g

Step 2: 

Check the method with a second example

If you want half the recipe:

Flour: 150 × 0.5 = 75 g

Sugar: 100 × 0.5 = 50 g

Butter: 50 × 0.5 = 25 g

Step 3: 

Use proportional reasoning to confirm

Original total flour for two batches/cakes:

150 × 2 = 300 g

One and a half batches should be less than 300 g.

Your scaled amount was 225 g, which is correct.

Step 4: Apply the method to any ingredient

Multiply the original quantity by the fraction you need.

This works for liquids, spices or mixed ingredients.

Skills that Count Check

Always convert mixed numbers to decimals before multiplying.

Scaling up increases every ingredient by the same fraction.

Scaling down reduces them equally.
