FAQs on Proportion Video Lecture - Mathematics Class 6 ICSE

1. What is a proportion in mathematics?
Ans. A proportion is an equation that states that two ratios are equal. For example, if we say that the ratio of boys to girls in a class is 2:3, we can express this as a proportion by saying 2/3 = 4/6, which shows that both ratios represent the same relationship.
2. How do you solve a proportion?
Ans. To solve a proportion, you can use cross-multiplication. This means you multiply the numerator of one ratio by the denominator of the other ratio and set them equal to each other. For instance, if you have the proportion a/b = c/d, you would multiply a by d and b by c, resulting in ad = bc. Then, you can solve for the unknown variable.
3. What are some real-life examples of proportions?
Ans. Proportions are commonly used in real life, such as in cooking (adjusting recipes), in maps (scales), and in finances (calculating discounts). For example, if a recipe calls for 2 cups of flour to make 12 cookies, you can use proportions to figure out how much flour is needed to make 24 cookies.
4. Why are proportions important in everyday life?
Ans. Proportions are important because they help us compare quantities and make informed decisions based on those comparisons. Whether it’s figuring out the right amount of ingredients for a recipe, understanding scale on a map, or calculating the price of items on sale, proportions allow us to maintain the correct relationships between different quantities.
5. How can I practice solving proportions?
Ans. You can practice solving proportions by using worksheets available online, engaging in math games that focus on ratios and proportions, or working with real-life scenarios. Additionally, textbooks often have practice problems, and you can also create your own examples to solve, such as comparing prices or quantities in everyday situations.
