2. 1/7 * 1. 2/5 = 15/7 * 7/5 = 3/1 * 1/1 = 3/1 = 3

Answer 3

Calculating the expression:

Let's break down the calculation step-by-step: 1) 2 + 1/7 * 1 + 2/5 = 2 + (1/7) * 1 + (2/5) = 2 + 1/7 + 2/5 = 2 + 0.142857 + 0.4 = 2.571429

So the value of the expression 2 + 1/7 * 1 + 2/5 is approximately 2.57 or 2 1/2.

Explaining the calculation:

To solve an expression involving multiple operations, we evaluate it from left to right following the order of operations (PEMDAS): - Parentheses first: There are no parentheses - Exponents: There are no exponents - Multiplication/Division: 1/7 * 1 is evaluated as 1/7. 2/5 is evaluated as 2/5. - Addition/Subtraction: The terms are added from left to right: 2 + 1/7 + 2/5.

Let me know if you need any part of the calculation explained further! Calculating step-by-step and following the proper order of operations is important for getting the right solution.
