Final answer:
The expression 2.2 x 5 - 11 + 6.6 ÷ 3 simplifies to 2.2 after following the order of operations (PEMDAS), in which multiplication and division are performed before addition and subtraction.
Step-by-step explanation:
The question asks to solve the mathematical expression 2.2 x 5 - 11 + 6.6 ÷ 3. To solve this problem, we must follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). First, we do the multiplication and division from left to right, then we proceed with the addition and subtraction.
Solving step-by-step:
- Multiplication: 2.2 x 5 = 11.
- Division: 6.6 ÷ 3 = 2.2.
- Now substitute these results into the original expression: 11 - 11 + 2.2.
- Addition/Subtraction: 11 - 11 = 0, then 0 + 2.2 = 2.2.
The final answer is 2.2.
