KnowledgeBoat · Accepted Answer

(i) and We have: + Let us find L.C.M. of denominators 3 and 4 L.C.M. = 2 x 2 x 3 = 12 Now, expressing each fraction with denominator 12: Hence, the answer is (ii) and We have: + Let us find L.C.M. 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 (iii) and We have: + Let us find LCM of denominators 18 and 27 L.C.M. = 3 x 3 x 3 x 2 = 54 Now, expressing each fraction with denominator 54: Hence, the answer is (iv) and We have: + Let us find LCM of denominators 12 and 24 L.C.M. = 2 x 2 x 3 x 2 = 24 Now, expressing each fraction with denominator 24: Hence, the answer is (v) and We have: + LCM of denominators 18 and 27 L.C.M. = 3 x 3 x 3 x 2 = 54 Now, expressing each fraction with denominator 54 . Hence, the answer is (vi) and We have: + First, multiply the numerator and denominator of by -1 to make denominator positive: . LCM of denominators 4 and 8 L.C.M. = 2 x 2 x 2 = 8 Now, expressing each fraction with denominator 8: Hence, the answer is
