Here’s a blog post explaining how to solve the pizza ingredient ratio problem:

Pizza Ingredient Ratios: Calculating Cheese and Topping

Let’s dive into a problem involving ratios and scaling ingredients, perfect for anyone who loves pizza! This is a practical application of math that can be used in cooking and baking.

The Problem:

Rosa prepares ingredients for pizzas. She uses cheese, topping, and dough in the ratio 2 : 3 : 5. Rosa uses 70 grams of dough. We need to work out the number of grams of cheese and the number of grams of topping Rosa uses.

1. Understand the Ratio

The ratio of cheese : topping : dough is 2 : 3 : 5. This means for every 2 parts of cheese, there are 3 parts of topping and 5 parts of dough.

2. Find the Value of One “Share”

We know Rosa uses 70 grams of dough, which corresponds to 5 “shares” in the ratio. To find the value of one share, divide the weight of the dough by the number of shares for dough:

70 grams / 5 shares = 14 grams/share

3. Calculate the Amount of Cheese

The ratio for cheese is 2 shares. Multiply the value of one share by 2:

2 shares * 14 grams/share = 28 grams

4. Calculate the Amount of Topping

The ratio for topping is 3 shares. Multiply the value of one share by 3:

3 shares * 14 grams/share = 42 grams

Answer:

Rosa uses 28 grams of cheese and 42 grams of topping.
