FAQs on Learning Poster: Ratio and Proportion - Mathematics Class 8- New NCERT (Ganita Prakash)

1. What is the definition of ratio and how is it used in daily life?
Ans. A ratio is a comparison between two or more quantities that shows how much of one thing exists in relation to another. Ratios are used in various daily life scenarios, such as cooking (e.g., mixing ingredients in specific proportions), financial planning (e.g., comparing income to expenses), and even in sports (e.g., comparing scores).
2. How do you calculate the proportion of two numbers?
Ans. To calculate the proportion of two numbers, you divide one number by the other. The result can be expressed as a fraction, decimal, or percentage. For example, if you have 4 apples and 8 oranges, the proportion of apples to oranges is 4/8, which simplifies to 1/2 or 50%.
3. Can you explain the difference between a ratio and a fraction?
Ans. Yes, a ratio shows the relationship between two quantities, often expressed in the form of "a:b" or "a/b", indicating how many times one quantity contains another. A fraction, on the other hand, represents a part of a whole, expressed as "a/b", where "a" is the numerator, and "b" is the denominator. While both can look similar, their interpretations differ.
4. What is the importance of understanding ratios and proportions in mathematics?
Ans. Understanding ratios and proportions is crucial in mathematics as they form the foundation for more advanced concepts. They help in solving problems related to scaling, comparisons, and distributions. Mastery of these concepts is essential for subjects like geometry, algebra, and statistics, as they apply to real-world situations.
5. How can 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 a ratio of 12:16, the GCD of 12 and 16 is 4. Dividing both numbers by 4 gives you the simplified ratio of 3:4.
