For Class 6 Mathematics, explain or solve a prime and composite numbers question from the chapter "Playing with Numbers". Focus on formula warm-up and show the working clearly.
Step-by-step solution path
Read the topic idea: Prime and Composite Numbers.
Recall the core explanation from the chapter: Factors, multiples, prime numbers, HCF and LCM โ the building blocks of number theory.
Use the related formula "Divisibility by 9" as the main tool while solving.
Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Prime and Composite Numbers. A strong solution should identify the correct data, apply Divisibility by 9, and explain each transition instead of jumping directly to the answer.
