Understanding Percentages: Calculating 7 out of 12 as a Percentage
When working with percentages, it's important to understand what a percentage represents. A percentage always indicates a part of a whole, where the whole is considered to be 100 units. In the question at hand, we need to determine what percent 7 is out of 12.
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. For example, if you have 50 out of 100, this is 50%. Similarly, if you have 7 out of 12, you can convert this to a percentage to get a clearer understanding of its proportion relative to the whole.
Step-by-Step Calculation
To find the percentage, follow these steps:
Write the formula for calculating the percentage: Percentage (Part / Whole) times; 100 Identify the 'Part' and 'Whole' Substitute the values into the formula: 7 / 12 times; 100 Perform the division: 0.5833333333 Multiply by 100 to convert to a percentage: 58.33333333%Alternative Methods and Insights
Several students and experts have provided alternative methods to solve this problem:
Grade IX Student's Approach
The student, unfamiliar with advanced concepts, employs a simple percentage formula: 7 / 12 0.58 0.58 times; 100 58
