Answer 3

To solve the expression, you need to perform the arithmetic operations in the given order of operations (parentheses, multiplication/division from left to right, addition/subtraction from left to right). Let's break it down step by step:

First, let's simplify the expression inside the parentheses: — 35/57 = -35/57 (since the negative sign applies to the entire fraction)

Next, let's multiply the two fractions: 19/40 * (-35/57) = (19 * -35) / (40 * 57) = -665 / 2280

The fraction -665/2280 cannot be simplified further. Therefore, the final answer is -665/2280.
