FAQs on Ratio Video Lecture - Mathematics Class 6 ICSE

1. What is a ratio and how is it represented?
Ans. A ratio is a way to compare two or more quantities by division. It shows how much of one thing there is compared to another. Ratios are typically expressed in the form "a:b" or as a fraction "a/b," where "a" and "b" are the quantities being compared.
2. How do you simplify a ratio?
Ans. To simplify a ratio, you divide both parts of the ratio by their greatest common divisor (GCD). For example, if you have the ratio 8:12, the GCD of 8 and 12 is 4. Dividing both parts by 4 gives you the simplified ratio of 2:3.
3. Can ratios be used to compare more than two quantities?
Ans. Yes, ratios can compare more than two quantities. For instance, if you have three quantities, such as 4, 6, and 8, you can express the ratio as 4:6:8. This means for every 4 parts of the first quantity, there are 6 parts of the second, and 8 parts of the third.
4. How do you convert a ratio into a percentage?
Ans. To convert a ratio into a percentage, you first convert the ratio into a fraction and then multiply by 100. For example, to convert the ratio 3:1 to a percentage, you write it as 3/1 = 3. Then, multiply by 100 to get 300%.
5. What are some real-life examples of ratios?
Ans. Ratios are commonly used in various real-life situations, such as in cooking (e.g., ingredients ratio), in finance (e.g., debt-to-income ratio), and in sports (e.g., wins to losses). They help in making comparisons and decisions based on quantitative information.
