Calculating the Expression

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's break down the expression step by step:

1. Calculate (5/9 - 11/12) * 3 + 9/12: - Start by finding the common denominator for 9 and 12, which is 36. - Then, convert the fractions to have the common denominator and perform the subtraction. - Next, multiply the result by 3 and add 9/12.

2. Calculate (0.3125 + 5/24) * 4 + 4/5: - Add 0.3125 and 5/24, then multiply the result by 4. - Finally, add 4/5 to the previous result.

Let's proceed with the calculations.

Step 1: Calculate (5/9 - 11/12) * 3 + 9/12

- Calculate the first part: (5/9 - 11/12): - The common denominator for 9 and 12 is 36. - Converting 5/9 to have a denominator of 36: 20/36. - Converting 11/12 to have a denominator of 36: 33/36. - Subtracting: 20/36 - 33/36 = -13/36.

- Multiply the result by 3: - (-13/36) * 3 = -39/36 = -1.0833 (rounded to 4 decimal places).

- Add 9/12: - Converting 9/12 to have a denominator of 36: 27/36. - Adding: -1.0833 + 27/36 = -0.5833 (rounded to 4 decimal places).

Step 2: Calculate (0.3125 + 5/24) * 4 + 4/5

- Add 0.3125 and 5/24: - Converting 0.3125 to a fraction with a denominator of 24: 7/24. - Adding: 7/24 + 5/24 = 12/24 = 1/2.

- Multiply the result by 4: - (1/2) * 4 = 2.

- Add 4/5: - Converting 4/5 to have a denominator of 5: 4/5. - Adding: 2 + 4/5 = 2.8.

Final Result:

The value of the given expression is approximately 2.8.
