Understanding Percentages in Mathematics
This page provides a comprehensive overview of percentages, including how to find percentage of boys and girls in maths and various conversion methods. The content is designed to help students grasp the fundamental concepts of percentages and their practical applications.
The page begins by introducing the basic percentage formula with example. It states that to find a percentage, you multiply by 100%. This is illustrated with a practical example:
Example: In a class with 5 total students, 2 are girls and 3 are boys. To find the percentage of girls, the calculation is: (2 ÷ 5) × 100 = 40%
The document emphasizes the importance of simplification in percentage calculations. It then moves on to explain how to convert percentages to fractions:
Highlight: To convert a percentage to a fraction, multiply by 1/100 and simplify.
Two examples are provided to demonstrate this process:
- Converting 60% to a fraction: 60% = 60 × (1/100) = 60/100 = 3/5
- Converting 62% to a fraction: 62% = 62 × (1/100) = 31/50
The page concludes with instructions on converting percentages to decimals:
Definition: To convert a percentage to a decimal, multiply by 1/100 and simplify if possible.
Examples of percentage to decimal conversions are given:
- 40% = 40 × (1/100) = 0.4
- 4% = 4 × (1/100) = 0.04
These examples serve as a percentage to decimal converter guide for students. The page effectively covers key aspects of percentage calculations, providing a solid foundation for students to understand and apply these concepts in various mathematical scenarios.
