A granola recipe uses 750 grams of oats for 15 servings. How many servings can be made with 450 grams of oats when every ingredient is reduced by the same factor?

Explication

Each serving uses 750 divided by 15, or 50 grams of oats, so 450 grams makes 9 servings. Choosing 10 servings treats 450 as roughly two-thirds of 750 without applying the exact factor of 0.6.
