Answer 3

To solve the expression 2 + 2/5 ÷ 0.4 - 2.40, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. First, we need to perform the division 2/5. This gives us 0.4. 2. Next, we need to perform the division 0.4 ÷ 0.4. This gives us 1. 3. Then, we perform the addition 2 + 1. This gives us 3. 4. Finally, we perform the subtraction 3 - 2.40. This gives us 0.60.

Therefore, the value of the expression 2 + 2/5 ÷ 0.4 - 2.40 is 0.60.
