Question

KnowledgeBoat · Accepted Answer

(i) Since the denominators are already the same and positive, we simply add the numerators. Hence, the answer is (ii) Since the denominators are already the same and positive, we simply add the numerators. Hence, the answer is (iii) Express numbers as positive denominators: . LCM of denominators = LCM (1, 3, 6): LCM = 3 x 2 = 6. Now, expressing each fraction with denominator 6: Hence, the answer is (iv) LCM of denominators = LCM (26, 13, 1): LCM = 13 x 2 = 26. Now, expressing each fraction with denominator 26: Hence, the answer is (v) LCM of denominators = LCM (1, 8, 4): LCM = 2 x 2 x 2 = 8. Now, expressing each fraction with denominator 8: Hence, the answer is (vi) LCM of denominators = LCM (8, 16, 4): LCM = 2 x 2 x 2 x 2 = 16. Now, expressing each fraction with denominator 16: . Hence, the answer is
