Answer 2

Solution:

To solve the given expression, we'll follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to simplify the expression step by step.

1. Convert Mixed Numbers to Improper Fractions: - 1 whole = 48/48 - 2 whole = 96/48 - 9 whole = 432/48

2. Simplify the Expression: - 1 whole + 1/48 = 48/48 + 1/48 = 49/48 - 2 whole + 2/5 = 96/48 + 19/48 = 115/48 - 9 whole + 1/6 = 432/48 + 8/48 = 440/48 - 2 whole + 5/9 = 96/48 + 40/48 = 136/48

3. Perform the Multiplication and Subtraction: - (49/48) * (115/48 - 440/48 * 4/15 * 136/48) * (1/4)

4. Calculate the Result: - (49/48) * (115/48 - 440/48 * 4/15 * 136/48) * (1/4) = 49/48 * (115/48 - 440/48 * 4/15 * 136/48) * 1/4

5. Final Result: - The final result of the expression is 49/48 * (115/48 - 440/48 * 4/15 * 136/48) * 1/4.
