Question

KnowledgeBoat · Accepted Answer

(i) First, express with a positive denominator: . Let us find LCM of denominators 3 and 9 L.C.M. = 3 x 3 = 9 Now, Hence, the answer is (ii) Let us find LCM of denominators 2 and 4. L.C.M. = 2 x 2 = 4 Now, Hence, the answer is (iii) First, express with a positive denominator: . Let us find LCM of denominators 9 and 6. L.C.M. = 3 x 3 x 2 = 18 Now, expressing each fraction with denominator 18: Hence, the answer is (iv) Express 2 as . LCM of denominators 1 and 4 is 4. Now, Hence, the answer is (v) Express 3 as . LCM of denominators 1 and 6 is 6. Now, Hence, the answer is (vi) Express -4 as . LCM of denominators 1 and 3 is 3. Now, Hence, the answer is
