Key Concepts

Ratio

A ratio expresses the quantitative relationship between two numbers, indicating how many times one quantity contains another. It forms the basis of calculating unit rates by comparing items like fat, carbohydrates, or protein to weight.

Rounding

Rounding involves adjusting a numerical value to a specified degree of precision, such as two decimal places. This ensures that results are both comprehensible and consistent when dealing with measurements that require standardization.

Unit Rate

A unit rate measures a quantity relative to a single unit of another quantity, often found by dividing one quantity by a given number of units. This concept is useful for comparing values on a common basis, such as calories per ounce or grams per ounce.
