So, let's embark on a mathematical journey and explore the concept of 90% of 80, unraveling its implications and significance along the way.


Introduction

In mathematics, calculating percentages is a fundamental skill. It helps us understand the relationship between different values and express them as proportions or ratios. One common percentage calculation is finding a specific percentage of a given number. In this article, we will explore how to determine 90% of 80 using simple mathematical operations.

Understanding Percentages

Before diving into the calculation, it's important to have a clear understanding of percentages. A percentage is a way of expressing a part of a whole as a fraction out of 100. For example, 50% represents half of something, while 100% represents the entire entity. Percentages are denoted by the symbol %.

The Calculation Process

To find what 90% of 80 is, we need to follow a simple calculation process. We can think of it as multiplying 80 by the decimal form of 90%. Remember that percentages can also be expressed as decimals, where 100% is equal to 1. So, to calculate 90% of 80, we multiply 80 by 0.9 (the decimal form of 90%).

Multiplying the Decimal

To convert a percentage to its decimal form, we divide it by 100. In this case, we divide 90 by 100, which gives us 0.9. Now, we can multiply this decimal by 80 to find the answer.

Applying the Calculation

Using the multiplication operation, we multiply 80 by 0.9. This can be done by multiplying the two numbers without the decimal point and then placing the decimal point in the product. When we perform this calculation, we get the result of 72.

Interpretation

So, 90% of 80 is equal to 72. This means that if we take 90% of the value 80, it will be 72. In other words, 72 is 90% of 80. This can be understood as taking a significant portion of the original value.

Other Examples

Let's consider a few more examples to solidify our understanding. If we want to find 90% of 100, we follow the same process: multiply 100 by 0.9. The result will be 90. Similarly, if we calculate 90% of 50, we would get 45. These examples demonstrate that finding a percentage of a number involves scaling it down by the given percentage.

Decimal to Percentage Conversion

It's worth noting that we can convert decimals back to percentages if needed. To convert a decimal to a percentage, we multiply it by 100 and add the % symbol. For instance, if we have the decimal 0.9, we can convert it to the percentage 90% by multiplying it by 100.

Practical Applications

Understanding how to calculate percentages is highly useful in various real-life situations. For example, when shopping during a sale, finding a percentage off an item's original price helps determine the discounted amount. Additionally, percentages are frequently used in finance, statistics, and many other fields.

Conclusion

In conclusion, determining what 90% of 80 is requires converting the percentage to its decimal form and multiplying it by the given number. By applying these simple mathematical operations, we find that 90% of 80 equals 72. Remembering this calculation method will enable you to easily find percentages of different values and apply it to various practical scenarios.
