Worked Example
Exam recap 10
For Class 10 Mathematics, explain or solve a decimal expansions of rational numbers question from the chapter "Real Numbers". Focus on exam recap and show the working clearly.
Step-by-step solution path
- Read the topic idea: Decimal Expansions of Rational Numbers.
- Recall the core explanation from the chapter: Class 10 NCERT chapter on Euclid’s division lemma, prime factorisation, irrational numbers and decimal expansions.
- Use the related formula "Euclid Division Lemma" 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 Decimal Expansions of Rational Numbers. A strong solution should identify the correct data, apply Euclid Division Lemma, and explain each transition instead of jumping directly to the answer.
