Definition

The percent one number is of another is a way to express one number as a percentage of another number.

Description

Understanding how to express one number as a percentage of another is crucial in various real-world applications, such as calculating discounts, tax, and interest rates. For example, if you want to find out what percentage 25 is of 200, you divide 25 by 200 and multiply by 100, resulting in 12.5%.

In math education, this concept helps students develop a deeper understanding of percentages and their applications. For instance, if a student scores 45 out of 60 on a test, they can calculate their percentage score by dividing 45 by 60 and multiplying by 100, which equals 75%. This skill is essential for interpreting data and making informed decisions based on percentage values.

Teacher’s Script: "To find out what percentage 30 is of 150, divide 30 by 150 and multiply by 100. This gives you 20%, meaning 30 is 20% of 150."
