Answer 1

Answer:

3(4/5)] + [2(3/10)] + [1(1/15)] First convert each mixed fraction into improper fraction. We get, = [3(4/5)] = (18/5) = [2(3/10)] = (23/10) = [1(1/15)] = (16/15) Then, (19/5) + (23/10) + (16/15) LCM of 5, 10, 15 = 30 Now, let us change each of the given fraction into an equivalent fraction having 30 as the denominator. = [(19/5) × (6/6)] = (114/30) = [(23/10) × (3/3)] = (69/ 30) = [(16/15) × (2/2)] = (32/30) Now, = (114/30) + (69/30) + (32/30) = [(114+69+32)/30] = (215/30) = [7 (5/30)] = [7 (1/5)]Read more on Sarthaks.com - https://www.sarthaks.com/741461/find-the-sum-3-4-5-2-3-10-1-1-15
