FAQs on Percentage - 1 Video Lecture - Mathematics Class 6 ICSE

1. What is percentage and how is it calculated?
Ans. A percentage is a way of expressing a number as a fraction of 100. To calculate a percentage, you divide the part by the whole and then multiply by 100. For example, if you scored 25 out of 50 on a test, you would calculate your percentage by dividing 25 by 50, which equals 0.5, and then multiplying by 100 to get 50%.
2. How can percentages be used in real-life situations?
Ans. Percentages are used in various real-life situations such as calculating discounts during shopping, determining interest rates for loans or savings, and analyzing data in statistics. For instance, if a shirt costs $40 and is on sale for 25% off, you can calculate the discount by finding 25% of 40, which is $10, making the sale price $30.
3. What are the common mistakes to avoid when working with percentages?
Ans. Common mistakes when working with percentages include forgetting to convert the percentage into a decimal before calculations, mixing up the part and whole when calculating, and misreading percentage increase or decrease. Always double-check your calculations and ensure you understand the context of the percentage.
4. How do you convert a percentage to a fraction?
Ans. To convert a percentage to a fraction, write the percentage number over 100 and simplify if possible. For example, to convert 75% to a fraction, write it as 75/100, which simplifies to 3/4 by dividing both the numerator and denominator by 25.
5. Why is it important to understand percentages in school?
Ans. Understanding percentages is important in school as it helps students develop critical math skills needed for higher-level math, science, and everyday decision-making. It also aids in interpreting information from graphs, making informed choices in financial matters, and understanding data in various subjects.
