Answer 3

To solve the expression:

0.545 ÷ 0.5 + 2.75 * 0.4 - 0.45 * 3.8

Follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left-to-right), Addition and Subtraction (left-to-right)):

1. Perform multiplication and division from left to right:

0.545 ÷ 0.5 = 1.09 2.75 * 0.4 = 1.1 0.45 * 3.8 = 1.71

Now the expression becomes:

1.09 + 1.1 - 1.71

2. Perform addition and subtraction from left to right:

1.09 + 1.1 = 2.19 2.19 - 1.71 = 0.48

So, the final answer is 0.48.
