Question

KnowledgeBoat · Accepted Answer

(i) We have: L.C.M. of 6 and 8 is 24. Now, expressing each fraction with denominator 24: Hence, the answer is (ii) We have: L.C.M. of 12 and 18 is 36. Now, expressing each fraction with denominator 36: Hence, the answer is (iii) we have: L.C.M. of 15 and 20 is 60. Now, expressing each fraction with denominator 60: Hence, the answer is (iv) We have: L.C.M. of 9 and 3 is 9. Now, expressing each fraction with denominator 9: Hence, the answer is (v) We have: L.C.M. of 11 and 4 is 44. Now, expressing each fraction with denominator 44: Hence, the answer is (vi) We have: L.C.M. of 3 and 4 is 12. Now, expressing each fraction with denominator 12: Hence, the answer is
