Answer 2

To solve this expression, follow the order of operations: Parentheses, Multiplication and Division, and finally Addition and Subtraction (often remembered using the acronym PEMDAS).

First, let's calculate the expression inside the parentheses:

14 3/7 × 2/7 = (14 + 3/7) × 2/7 = (105/7 + 3/7) × 2/7 = (108/7) × 2/7 = 216/49

Now, multiply this result by 2 1/2:

2 1/2 × (216/49) = (5/2) × (216/49) = (5 * 216) / (2 * 49) = 1080 / 98 = 54 / 49

So, 2 1/2 × (14 3/7 × 2/7) is equal to 54/49.
