Answer 2

Calculating the Expression

To solve the given expression (2.35 + 4.65) * 5.3 / (40 - 2.9), we can follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's perform the operations inside the parentheses: - (2.35 + 4.65) = 7 - (40 - 2.9) = 37.1

Now, we can substitute these values back into the expression: - 7 * 5.3 / 37.1

Next, we perform the multiplication and division from left to right: - 7 * 5.3 = 37.1 - 37.1 / 37.1 = 1

So, the result of the expression (2.35 + 4.65) * 5.3 / (40 - 2.9) is 1.
