Real Number
In MP Board Class 10th Maths, Chapter 1 is "Real Numbers." This chapter mainly includes
concepts like Euclid's Division Lemma, Fundamental Theorem of Arithmetic, HCF & LCM, and
properties of irrational and rational numbers.
Here are the most expected questions that are frequently asked in exams:
1-Mark Questions:
1. Define an irrational number with an example.
2. Write one example of a rational and irrational number.
3. What is the HCF of two co-prime numbers?
4. Is √2 a rational or irrational number?
2-Mark Questions:
1. Find the HCF of 56 and 72 using Euclid’s Division Algorithm.
2. Write the decimal expansion of 7/8. it is terminating or non-terminating?
3. Express 98 as a product of its prime factors.
3-Mark Questions:
1. Use Euclid's division lemma to find the HCF of 135 and 225.
2. Find the LCM and HCF of 12 and 18 and verify that LCM × HCF = Product of the numbers.
