Answer 2

To solve the expression 11/50 × 3.3 + 2 + 4 + 1/2 × 5.4 ÷ 3 × 6.5 × 1/2, we need to follow the order of operations, also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Start with the multiplication and division from left to right:

11/50 × 3.3 = 0.22

1/2 × 5.4 = 2.7

2. Now, let's perform the addition and subtraction from left to right:
