3 X (1/2 + 1/3) =
A) 2,1/2 is the correct answer.
In this problem, the operation within the parentheses should be performed first, according to the order of operations (BIDMAS/BODMAS/PEDMAS). Adding 1/2 and 1/3 gives 5/6. Then, multiplying 5/6 by 3 gives 2,1/2.
This option is incorrect because it suggests that the multiplication was performed before the addition within the parentheses, which violates the order of operations. According to the BIDMAS/BODMAS/PEDMAS rule, operations enclosed in parentheses should be done first.
This answer is incorrect. It seems to suggest that each fraction within the parentheses was multiplied by 3 separately before being added, which again violates the order of operations.
This choice is incorrect as it incorrectly suggests that the sum of 1/2 and 1/3 equals 5/6, and then this sum was multiplied by 3 to get 3,5/6. However, this isn't the case. The sum 1/2 + 1/3 equals 5/6, and when multiplied by 3, it gives 2,1/2, not 3,5/6.
The correct answer to the operation 3 × (1/2 + 1/3) is 2,1/2. This solution follows the order of operations, also known as BIDMAS/BODMAS/PEDMAS, which requires calculations within parentheses to be done first. The other options incorrectly suggest that the order of operations was not followed, which leads to wrong results.
