How to Find Percentage: The Method
To find a percentage, divide the number by the total and multiply by 100.
For example, if you want to find the percentage of people who are taller than 6 feet, divide the number of people who are taller than 6 feet by the total number of people and multiply by 100.
In this example, there are 9 people who are taller than 6 feet.
9 ÷ 20 × 100 = 45%
Percentage Explanation with Examples
- Percentage is a type of ratio that compares two numbers by indicating what part one number is of the other. It is written using the percent symbol (%), and it is always expressed as a number between 0 and 100. For example, 33% means that 33 is the part of 100.
- To find a percentage, divide the number of interest by the total number and multiply by 100.
- For example, if you want to find the percentage of males in a class of 30 students, divide the number of males (15) by the total number of students (30) and multiply by 100. This gives you a percentage of 50%. In other words, 50% of the students in the class are male.
- Here are some other examples:
- – If you want to find the percentage of people who voted for a particular candidate, divide the number of people who voted for that candidate by the total number of people who voted and multiply by 100.
- – If you want to find the percentage of people who are taller than 6 feet, divide the number of people who are taller than 6 feet by the total number of people and multiply by 100.
