(a) \( \pi \) (b) \( \sqrt{5} \) (c) 0.101001000100001 … (d) 0.835835835 … Solution Option (a): \( \pi \) ✘ Irrational \( \pi \) is non-terminating and non-repeating. Option (b): \( \sqrt{5} \) ✘ Irrational \( \sqrt{5} \) cannot be expressed […]

Convert 1.6 Bar into Fraction MCQ Question The simplest form of \(1.\overline{6}\) is: (a) \( \frac{8}{5} \) (b) \( \frac{5}{3} \) (c) \( \frac{833}{500} \) (d) \( \frac{7}{6} \) Solution Let \( x = 1.\overline{6} \) \[ x = 1.6666\ldots \] Multiply both sides by 10: \[ 10x = 16.6666\ldots \] Subtract the first equation

Convert 0.4 Bar into Fraction MCQ Question The value of \(0.\overline{4}\) in the form \( \frac{p}{q} \), where \(q \neq 0\), is: (a) \( \frac{4}{9} \) (b) \( \frac{2}{5} \) (c) \( \frac{1}{5} \) (d) \( \frac{4}{5} \) Solution Let \( x = 0.\overline{4} \) Then, \[ x = 0.4444\ldots \] Multiply both sides by

Irrational Number from Decimal Expansion MCQ Question Which of the following is an irrational number? (a) 0.13 (b) 0.1315 (c) 0.1315 (d) 0.301323100523 … Solution Option (a): 0.13 ✘ Rational This is a terminating decimal, so it is rational. Option (b): 0.1315 ✘ Rational This is also a terminating decimal, hence rational. Option (c): 0.1315

Decimal Representation of Irrational Numbers MCQ Question A number is irrational if and only if its decimal representation is: (a) non-terminating (b) non-terminating and repeating (c) non-terminating and non-repeating (d) terminating Solution An irrational number cannot be expressed in the form \( \frac{p}{q} \). Its decimal expansion has two important properties: It is non-terminating (never

Decimal Expansion of Rational Numbers MCQ Question The decimal expansion of a rational number is: (a) terminating or non-terminating non-repeating (b) terminating or non-terminating repeating (c) terminating and repeating (d) none of these Solution A rational number can be written in the form \( \frac{p}{q} \), where \( q \neq 0 \). Its decimal expansion

Classification of Real Numbers Classification of Real Numbers Fill in the Blank: Every real number is either rational or irrational number. Explanation: Real numbers include all numbers on the number line. These are classified into: Rational numbers (can be written as \( \frac{p}{q} \)) Irrational numbers (cannot be written as \( \frac{p}{q} \)) Final Answer:
