Answer 3

To solve this expression, 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 down the expression step by step:

1. First, simplify the expressions within the parentheses: 45 ÷ (90 32/21)

   To simplify this further, calculate the value inside the parentheses: 90 + 32/21

   Now, find a common denominator to add these fractions: 90 = (90 * 21/21) = 1890/21 32/21

   So, the expression inside the parentheses becomes: 1890/21 + 32/21

   Combine the fractions: (1890 + 32) / 21 = 1922/21

2. Now, substitute this value back into the main expression: 2 270/123 + 6 745/87 * (-432 + 1922/21)

3. Next, calculate the multiplication within the parentheses: 6 745/87 * (-432 + 1922/21)

   To do this, we need to find a common denominator for -432 and 1922/21: -432 = (-432 * 21/21) = -9072/21 1922/21

   Now, the expression becomes: 6 745/87 * (-9072/21 + 1922/21)

4. Combine the fractions inside the parentheses: (745/87) * (-9072/21 + 1922/21)

5. Calculate the sum inside the parentheses: (-9072/21 + 1922/21) = (-7150/21)

6. Substitute this value back into the main expression: 2 270/123 + (745/87) * (-7150/21)

7. Calculate the multiplication in the main expression: (745/87) * (-7150/21)

8. Now, multiply the fractions: (745 * -7150) / (87 * 21) = -5356750 / 1827

9. Finally, add this result to the first part of the expression: 2 270/123 + (-5356750 / 1827)

You can leave the answer as an improper fraction, or you can convert it to a mixed number if needed. If you need further simplification or decimal approximation, you can perform those calculations as well.
