FAQs on Examples: Ratios Proportion- 2 Video Lecture - Mathematics for Grade 6

1. What is the definition of ratio in mathematics?

Ans. Ratio is a mathematical concept that represents the relationship between two or more quantities. It is expressed as the quotient or division of one quantity by another, and it shows how many times one quantity is greater or smaller than another.

2. How can ratios be used in real life situations?

Ans. Ratios have various applications in real life situations. For example, they can be used to compare ingredients in a recipe, determine the scale of a map or model, calculate exchange rates for currency conversion, or even analyze financial statements and business performance.

3. What is the difference between a ratio and a proportion?

Ans. While both ratios and proportions involve comparing two or more quantities, there is a subtle difference between the two. A ratio is a simple comparison of quantities, whereas a proportion is an equation that states that two ratios are equal. In other words, a proportion is a statement of equality between two ratios.

4. How can ratios be simplified?

Ans. Ratios can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD). This process ensures that the ratio is expressed in its simplest form, with no common factors between the numerator and the denominator.

5. Can ratios be used to solve problems involving unknown quantities?

Ans. Yes, ratios can be used to solve problems with unknown quantities. By setting up a proportion with known ratios and an unknown quantity, it is possible to solve for the unknown value using cross-multiplication. This method is commonly used in various real-life scenarios, such as calculating unknown lengths or finding missing values in similar figures.
