FAQs on Typical problems on Ratio and Proportion [English]- Part 1 Video Lecture - Quantitative Techniques for CLAT

1. What is the concept of ratio and proportion?
Ans. Ratio and proportion are mathematical concepts used to compare quantities and establish relationships between them. A ratio compares two or more quantities, while a proportion states that two ratios are equal.
2. How can I find the missing term in a proportion?
Ans. To find the missing term in a proportion, you can use the cross-multiplication method. Multiply the numerator of one ratio with the denominator of the other ratio and set the two products equal to each other. Then, solve the resulting equation to find the missing term.
3. Can you provide an example of solving a ratio and proportion problem?
Ans. Sure! Let's say we want to find the missing term in the proportion 3/4 = x/12. To solve this, we can cross-multiply: 3 * 12 = 4 * x. Simplifying, we get 36 = 4x. Dividing both sides by 4, we find x = 9. Therefore, the missing term is 9.
4. How are ratios and proportions used in real-life situations?
Ans. Ratios and proportions are commonly used in various real-life situations. For example, they can be used in cooking to scale down or up a recipe, in finance to calculate interest rates or exchange rates, or in map scaling to determine distances accurately.
5. Can ratios and proportions be expressed as fractions or decimals?
Ans. Yes, ratios and proportions can be expressed as both fractions and decimals. For example, a ratio of 2:3 can be written as the fraction 2/3 or the decimal 0.67. Similarly, a proportion of 1:4 = 3:x can be written as the fraction 1/4 = 3/x or the decimal 0.25 = 3/x.
