Cooking and Recipes

Algebra in the Kitchen

Algebra is a secret ingredient in every recipe! Use variables and equations to adjust ingredient amounts for different servings.

Scaling Recipes

If a recipe serves 4 people but you have 6 guests, set up an equation to find out how much of each ingredient you need.

Proportions

Equations help you keep the right proportions so your food tastes delicious every time.

Everyday Benefits

Being able to adjust recipes with algebra saves food, time, and makes you a kitchen hero!

Examples

  • A recipe needs 2 cups of rice for 4 people. For 8 people: \( 2x = 2 \times 2 = 4 \) cups of rice.

  • If 1 cake serves 8, but you need to serve 24, make \( 24/8 = 3 \) cakes.
