## FAQs on Prime Time Class 6 Notes: CBSE Maths Chapter 5

1. What is Class 6 Maths Chapter 5 "Prime Time" about?

Class 6 Maths Chapter 5 "Prime Time" teaches you about prime numbers and composite numbers. It explains how to identify prime numbers (numbers that can only be divided by 1 and themselves) and composite numbers (numbers that have more than two factors).

2. Why are prime numbers important in Chapter 5 of Class 6 Maths?

Prime numbers are important because they are the building blocks of all other numbers. Understanding prime numbers helps us in various math problems and number patterns.

3. How can I identify a prime number in Class 6 Maths Chapter 5?

To identify a prime number, check if it can only be divided evenly by 1 and itself. For example, 2, 3, 5, and 7 are prime numbers because they don't have other divisors.

4. What are composite numbers in Class 6 Maths Chapter 5?

Composite numbers are numbers that have more than two factors. For example, 4, 6, and 8 are composite numbers because they can be divided evenly by numbers other than 1 and themselves.

5. How can Class 6 Maths Chapter 5 help with my exams?

Chapter 5 helps you understand the concepts of prime and composite numbers, which are important for solving various types of maths problems. Knowing these concepts will help you tackle questions related to factors, multiples, and number patterns in your exams.

6. What are factors, and how are they related to prime and composite numbers in Chapter 5?

Factors are numbers that divide another number exactly without leaving a remainder. For prime numbers, the only factors are 1 and the number itself. For composite numbers, there are additional factors besides 1 and the number itself.

7. Can you give an example of how to find if a number is prime or composite in Class 6 Maths Chapter 5?

Sure! To check if 13 is a prime number, see if it can be divided evenly by any numbers other than 1 and 13. Since it can only be divided by 1 and 13, it is a prime number. To check if 12 is composite, note that it can be divided by 1, 2, 3, 4, 6, and 12, so it is a composite number.

8. What are prime numbers used for in Class 6 Maths Chapter 5?

Prime numbers are used to find factors, solve problems involving multiples, and simplify fractions. They are fundamental in understanding how numbers work together in maths.

9. How do I use the Sieve of Eratosthenes in Chapter 5?

The Sieve of Eratosthenes is a method to find all prime numbers up to a certain limit. You start by listing numbers and then cross out multiples of each prime number, leaving only prime numbers.

10. What is the difference between a prime number and a composite number in Chapter 5?

A prime number has exactly two factors: 1 and itself. A composite number has more than two factors, meaning it can be divided evenly by numbers other than 1 and itself.

11. How does Class 6 Maths Chapter 5 help with learning multiplication?

Understanding prime and composite numbers helps with multiplication by showing how numbers can be broken down into smaller parts. This knowledge makes it easier to solve problems involving factors and multiples.

12. Why are there no prime numbers less than 2 in Chapter 5?

By definition, a prime number must be greater than 1 and have exactly two factors. The number 1 only has one factor (itself) and thus does not meet the definition of a prime number.

13. How do I practise identifying prime and composite numbers for Class 6 Maths Chapter 5?

To practice, you can create lists of numbers and test each one to see if it is prime or composite. Use methods like dividing by smaller numbers or applying the Sieve of Eratosthenes to find primes up to a certain limit.
