Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders (if any)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression is:

(1 25/100 - 1 1/3) * (-5 1/7) - 1 1/6 ÷ 5 4/9

Step 1: Convert all mixed numbers to improper fractions: 1 25/100 = (1 * 100 + 25) / 100 = 125/100 1 1/3 = (1 * 3 + 1) / 3 = 4/3 -5 1/7 = -(5 * 7 + 1) / 7 = -36/7 1 1/6 = (1 * 6 + 1) / 6 = 7/6 5 4/9 = (5 * 9 + 4) / 9 = 49/9

Step 2: Perform the operations inside the parentheses: (125/100 - 4/3) * (-36/7) - (7/6 ÷ 49/9)

Step 3: Perform the operations in the numerator and denominator of the division: (125/100 - 4/3) * (-36/7) - (7/6 * 9/49)

Step 4: Perform the operations in the parentheses again: [(125/100) - (4/3)] * (-36/7) - (63/294)

Step 5: Perform the operations in the brackets: [125/100 - 133/100] * (-36/7) - (63/294)

Step 6: Combine like terms: [-8/100] * (-36/7) - (63/294)

Step 7: Perform the multiplication: (8/100) * (-36/7) - (63/294)

Step 8: Simplify: -288/700 - 63/294

Step 9: Find a common denominator for subtraction: -288/700 - 2100/294

Step 10: Perform the subtraction: -288/700 - 7000/700 = (-288 - 7000) / 700 = -7288 / 700

Now, you can simplify the fraction or convert it to a mixed number if required. In this case, it is already simplified.

The final result is approximately -10.4114.
