Which of the following rational number is in the standard form? a) 16/21 b) 16/24 c) 21/15 d) −21/56 To identify the rational number in standard form, recall: A rational number is in standard form if: The numerator and denominator have no common factors other than 1 (i.e., they are co-prime), The denominator is positive. Let's check each option: a) 16/21 GCD of 16 and 21 is 1 → Co-prime Denominator is positive ✅ Standard form b) 16/24 GCD of 16 and 24 is 8 → Not co-prime ❌ Not in standard form c) 21/15 GCD of 21 and 15 is 3 → Not co-prime ❌ Not in standard form d) −21/56 GCD of 21 and 56 is 7 → Not co-prime ❌ Not in standard form ✅ Correct answer: a) 16/21 Rational Number ncert 8th maths, ncert 8th maths chapter 1, ncert 8th maths chapter 2, ncert 8th maths chapter 3, ncert 8th maths exercise 2.2, ncert 8th maths square and square roots, ncert 8th maths exercise 1.1, ncert 8th maths chapter 9, ncert 8th maths chapter 3.1, ncert 8th maths chapter 2.2, ncert 8th maths exercise 2.1, ncert class 8 maths algebraic expressions, ncert class 8 maths algebraic expressions and identities, ncert class 8 maths all chapter formulas, ncert class 8 maths annual exam question paper, ncert class 8 maths all chapter, ncert class 8 maths algebraic expressions 9.1, ncert exemplar class 8 maths algebraic expressions, ncert class 8th maths chapter 8 algebraic expressions and identities, class 8th ncert maths chapter 8 algebraic expressions, class 8th ncert maths chapter square and square roots,
