Answer 3

Calculation of (4 + 5/9 - 3 + 7/12) / (-1 + 8/27)

To solve the given expression (4 + 5/9 - 3 + 7/12) / (-1 + 8/27), 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 simplify the expression step by step:

1. Convert Mixed Numbers to Improper Fractions: - 5/9 can be converted to an improper fraction as (9 * 4 + 5) / 9 = 45/9 - 7/12 can be converted to an improper fraction as (12 * 0 + 7) / 12 = 7/12

2. Simplify the Numerator: - 4 + 45/9 - 3 + 7/12 = 4 + 5 - 3 + 7/12 = 6 + 7/12

3. Simplify the Denominator: - (-1 + 8/27) = (-27 + 8) / 27 = -19/27

4. Perform the Division: - (6 + 7/12) / (-19/27) = (6 + 7/12) * (-27/19)

Let's calculate the final result:

- (6 + 7/12) * (-27/19) = (6 * -27/19) + (7/12 * -27/19) - = -162/19 - 63/76 - = -162/19 - 63/76 - = -684/76 - 63/76 - = -747/76

So, the result of the expression (4 + 5/9 - 3 + 7/12) / (-1 + 8/27) is -747/76.
