Answer 2

Calculation Examples

Sure, I can help you with the three examples you provided. Let's solve them one by one:

Example 1: Calculate the expression: (12 + 3/7) * (-14/29)

To solve this, we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, let's simplify the expression inside the parentheses: 12 + 3/7 = 12 + 0.42857142857142855 = 12.428571428571429

Now, let's multiply the result by -14/29: 12.428571428571429 * (-14/29) = -6

Therefore, the solution to the expression (12 + 3/7) * (-14/29) is -6.

Example 2: Calculate the expression: (-1 + 1/3) : (-2/3)

Again, let's follow the order of operations.

First, let's simplify the expression inside the parentheses: -1 + 1/3 = -0.6666666666666666 + 0.3333333333333333 = -0.3333333333333333

Now, let's divide the result by -2/3: -0.3333333333333333 : (-2/3) = 0.5

Therefore, the solution to the expression (-1 + 1/3) : (-2/3) is 0.5.

Example 3: Calculate the expression: (-28 + 5/9) - (6 + 2/3)

Let's follow the order of operations once again.

First, let's simplify the expression inside the parentheses: -28 + 5/9 = -28 + 0.5555555555555556 = -27.444444444444443

6 + 2/3 = 6 + 0.6666666666666666 = 6.666666666666667

Now, let's subtract the second result from the first: -27.444444444444443 - 6.666666666666667 = -34.11111111111111

Therefore, the solution to the expression (-28 + 5/9) - (6 + 2/3) is -34.11111111111111.

I hope this helps! Let me know if you have any further questions.
