GoMim AI | What is percentage calculator and How to Calculate it

Introduction

In the world of mathematics, percentages are a fundamental concept used to express numbers as parts of a whole. We encounter percentages in various aspects of life, from sales discounts to statistical data interpretation. A percentage calculator can be an invaluable tool, simplifying the process of working with percentages. This article will explore what a percentage calculator is, its significance, and how to effectively use it for solving mathematical problems.

What is it?

A percentage calculator is a tool designed to simplify the computation of percentages. It helps users determine the percentage of a number or find out what number corresponds to a specific percentage of another number. The basic mathematical expression for percentage calculation is: $$ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 $$ where 'Part' is the portion or segment of the whole, and 'Whole' is the total or complete amount.

Why is it important?

The importance of a percentage calculator lies in its widespread applications. In academics, students often need to calculate percentages to understand their grades. In business, percentages are crucial for determining profit margins, discounts, and interest rates. Engineers use percentages to understand efficiency rates, and data analysts rely on them to interpret statistical results. By simplifying these calculations, a percentage calculator saves time and reduces the likelihood of errors.

How to Calculate it Step-by-Step

To calculate percentages using a percentage calculator, follow these steps:

1. Identify the Part and Whole: Determine which numbers represent the 'part' and the 'whole' in your context.
2. Use the Formula: Apply the formula $$ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 $$.
3. Perform the Calculation: Divide the part by the whole, then multiply the result by 100 to convert it into a percentage.

Example:

You scored 45 out of 60 on a test. To find your percentage score:

• Part = 45
• Whole = 60
• Calculation: $$ \left( \frac{45}{60} \right) \times 100 = 75\%$$

Thus, you scored 75%.

Related Practice Problem

Problem:

Imagine you are shopping, and an item originally priced at $80 is on sale for 20% off. What is the discounted price?

Step-by-step Solution:

1. Identify Original Price and Discount Percentage:
2. Original Price = $80
3. Discount Percentage = 20%
4. Calculate the Discount Amount:
5. Discount Amount = $$ \left( \frac{20}{100} \right) \times 80 = 16$$
6. Subtract the Discount from the Original Price:
7. Discounted Price = Original Price - Discount Amount
8. Discounted Price = $$ 80 - 16 = 64$$

Therefore, the discounted price of the item is $64.
