Answer 2

Calculation: a) 9 + 12/17 - (4 + 8/17 - 1 + 7/17)

To solve this calculation, we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

Let's break down the calculation step by step:

1. Simplify the expression inside the parentheses: - (4 + 8/17 - 1 + 7/17) = 4 + 8/17 - 1 + 7/17 = 4 + 15/17 = 4 + 0.8824 = 4.8824

2. Substitute the simplified expression back into the original calculation: - 9 + 12/17 - (4.8824)

3. Perform the subtraction inside the parentheses: - 9 + 12/17 - 4.8824 = 9 + 0.7059 - 4.8824 = 9 - 4.1765 = 4.8235

Therefore, the result of the calculation a) 9 + 12/17 - (4 + 8/17 - 1 + 7/17) is approximately 4.8235.

Calculation: b) 5 + 6/13 - (1 + 2/13 + 1 + 3/13)

Let's follow the same steps as above to solve this calculation:

1. Simplify the expression inside the parentheses: - (1 + 2/13 + 1 + 3/13) = 1 + 2/13 + 1 + 3/13 = 1 + 0.1538 + 1 + 0.2308 = 2.3846

2. Substitute the simplified expression back into the original calculation: - 5 + 6/13 - (2.3846)

3. Perform the subtraction inside the parentheses: - 5 + 6/13 - 2.3846 = 5 + 0.4615 - 2.3846 = 5 - 1.9231 = 3.0769

Therefore, the result of the calculation b) 5 + 6/13 - (1 + 2/13 + 1 + 3/13) is approximately 3.0769.
