**3. What are the topics covered in NCERT Solutions for Class 6 Maths Chapter 12?**

Class 6 Maths Chapter 12 talks in-depth about ratios, proportions, as well as the unitary method. We get equivalent ratios through multiplication or division of the denominator and numerator by a constant value. When the value of two ratios is equal, they are called proportionate. Here, the symbol ‘::’ is used to denote the same. The unitary method refers to the process in which the value of a single unit is calculated first to find out the value of the required number of units.

**4. What are the real-time applications of the unitary method?**

**The following are a few real-time applications of the unitary method:**

To calculate the speed for a particular distance, when the value of speed and distance are in different units.

To calculate the number of persons required for the completion of work.

To calculate the area of a square of any given length when the ratio of the area with its side is known.

To calculate the price of a given quantity of objects, when the price and quantity of objects are known by different units.

**5. What are the most important definitions that come in Class 6 Maths Chapter 12?**

**The most important definitions in ****Class 6 Maths**** Chapter 12 are as follows:**

Ratio- The comparison of two values with the help of division is called a ratio.

Proportion- when two ratios have equal values, they are known to be Proportional.

Unitary Method- the calculation of the value of one unit to find out the total number of units is known as the Unitary method.

6. What is a ratio in class 6 math exercise 12.1?

A ratio is a way to compare two quantities by dividing one by the other. It shows how many times one value contains another. For example, the ratio of 2 to 3 is written as 2:3 or 2/3. Ratios are fundamental in understanding relationships between numbers.In maths class 6 chapter 12 exercise 12.1 are used in various mathematical calculations and real-life scenarios.

7. How do you express a Ratio in Class 6th Maths Chapter 12 Exercise 12.1?

A ratio can be expressed in the form a/b or as a:b. Both notations indicate the same relationship between two quantities. For example, a ratio of 4 to 5 can be written as 4:5 or 4/5. Class 6th Maths Chapter 12 Exercise 12.1 helps in comparing quantities directly and understanding their proportionate relationships. Expressing ratios correctly is crucial for solving ratio problems accurately.

8. What is a proportion in 12.1 class 6 maths?

In 12.1 class 6 maths proportion is an equation that states two ratios are equal. It can be written as $\frac{a}{b}= \frac{c}{d}$ or a:b = c:d. Proportions are used to find unknown values when the relationship between quantities is consistent. They are essential in solving problems involving scales and maps. Understanding proportions helps in maintaining consistent relationships between different sets of quantities.

9. How do you simplify a ratio in maths class 6 chapter 12 exercise 12.1?

To simplify a ratio, divide both terms by their greatest common divisor (GCD). For example, to simplify the ratio 8:12, find the GCD of 8 and 12, which is 4, and then divide both terms by 4, resulting in the simplified ratio 2:3. Simplifying ratios makes them easier to work with and compare. This process helps in reducing ratios to their simplest form for clarity and ease of use.

10. What is the importance of ratios in daily life in class 6 ex 12.1?

In class 6 ex 12.1 Ratios are used in various real-life situations, such as cooking recipes, where ingredients must be mixed in specific proportions. They are also important in comparing prices, understanding map scales, and creating models. Ratios help in making informed decisions by comparing different quantities effectively. They are fundamental in fields like finance, engineering, and science, making them essential for everyday calculations.

11. What should students focus on class 6 maths ex 12.1?

Students should focus on practicing problems, understanding the concepts of ratios and proportions, and applying them to real-life situations.
