The numbers 105 and 330 are products of exactly three distinct prime numbers. Their factorizations are: 105 = 3 × 5 × 7, 330 = 2 × 3 × 5 × 11 (distinct count: 3). Class 6 NCERT Ganita Prakash Chapter ...
True. Among primes, only 2 and 3 are consecutive. For all other primes, the next number is either even or divisible by a smaller prime, making it composite. This holds universally for prime numbers. Class 6 NCERT Ganita Prakash Chapter 5 ...
False. While most even numbers are composite, the number 2 is an exception. It is the only even prime number because it has exactly two factors: 1 and 2, distinguishing it from composites. Class 6 NCERT Ganita Prakash Chapter 5 Prime ...
False. Prime numbers have exactly two factors: 1 and the number itself. For instance, 7 has only two factors: 1 and 7, which is what defines it as a prime number. Class 6 Mathematics Chapter 5 Prime Time question answer Class 6 ...
False. A product of two or more prime numbers is composite, not prime. A prime number has exactly two divisors, but the product of primes has additional divisors, including the prime factors themselves. Class 6 Mathematics Chapter 5 Prime Time question ...
True. A prime number’s units digit cannot be 4 because numbers ending in 4 are divisible by 2, making them even. All even numbers other than 2 are composite, disqualifying them from being prime. Class 6 Mathematics Chapter 5 Prime Time ...
CBSE Grade 6 Ganita Prakash Chapter 4 “Data Handling and Presentation” introduces data collection, organization using tally marks and tables, and visual representation through pictographs and bar graphs. It emphasizes practical applications, choosing accurate scales, and creating visually appealing yet ...
Ensure bar heights match data values (e.g., 1400 in 2006, 1700 in 2010). Maintain consistent scales on the vertical axis, starting from zero, and label all axes clearly for accurate interpretation. Class 6 Mathematics Ganita Prakash Data Handling and Presentation Class 6 ...
Multiply each wicket count (0–7) by its frequency and sum the results. For example: (0 × 2) + (1 × 4) + (2 × 6) + … + (7 × 1) = Total wickets. Class 6 Mathematics Ganita Prakash Data Handling ...
