Answer 3

To calculate the expression (66.15 - 22.05 / 2.1) * 6.4, 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).

Let's break it down step by step:

1. First, calculate the division inside the parentheses: 22.05 / 2.1 = 10.5

2. Now, subtract the result from step 1 from 66.15: 66.15 - 10.5 = 55.65

3. Finally, multiply the result from step 2 by 6.4: 55.65 * 6.4 = 356.16

So, (66.15 - 22.05 / 2.1) * 6.4 equals 356.16.
