Answer 2

To calculate the expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you should first perform the multiplication and division and then the addition and subtraction.

Let's break down the expression step by step:

1. Multiplication and Division: 2.7 * (-4/9) = -1.2 1.4 ÷ (7/8) = 1.6 4.6 * 0.5 = 2.3 5.5 ÷ 5 = 1.1

Now, we have: -1.2 - 1.6 + 2.3 - 1.1

2. Addition and Subtraction (left-to-right): -1.2 - 1.6 = -2.8 -2.8 + 2.3 = -0.5 -0.5 - 1.1 = -1.6

So, the final result of the expression is -1.6.
