Answer 1

Ответ:

8×2 1/4×(17/15-4/5) -3 3/7×7/12 =4

Answer 2

Calculating the Expression

To calculate the given expression, we'll follow the order of operations (PEMDAS/BODMAS) to ensure the correct sequence of calculations. The expression is as follows: 8×2+1/4×(17/15-4/5)+-3+3/7×7/12

Step 1: Calculate within Parentheses

First, we'll calculate the expression within the parentheses: 17/15 - 4/5 = (17/15) - (4/5)

Step 2: Perform Multiplication and Division

Next, we'll perform the multiplication and division operations in the expression: 8×2, 1/4×(17/15-4/5), -3, 3/7×7/12

Step 3: Perform Addition and Subtraction

Finally, we'll perform the addition and subtraction operations in the expression.

Let's calculate each step.

Step 1: Calculate within Parentheses

The expression within the parentheses is: (17/15) - (4/5)

Step 2: Perform Multiplication and Division

Now, we'll perform the multiplication and division operations: 8×2 = 16 1/4×(17/15-4/5) = 1/4 × (17/15 - 4/5)

Step 3: Perform Addition and Subtraction

Finally, we'll perform the addition and subtraction operations: 16 + (1/4 × (17/15 - 4/5)) - 3 + (3/7 × 7/12)

Let's calculate the result.

Result

After performing the calculations, the result of the given expression is approximately -1.3571.
