Answer 2

To evaluate the given expression:

(4,25 * 0,16 - 2,575 : 2,5) * 611 / 14 + 5 / 6

Let's break it down step by step:

Step 1: Simplify the expression within the parentheses. 4,25 * 0,16 = 0,68 2,575 : 2,5 = 1,03

The expression becomes: (0,68 - 1,03) * 611 / 14 + 5 / 6

Step 2: Perform the subtraction inside the parentheses. 0,68 - 1,03 = -0,35

The expression becomes: (-0,35) * 611 / 14 + 5 / 6

Step 3: Perform the multiplication and division from left to right. (-0,35) * 611 = -213,85 -213,85 / 14 = -15,275

The expression becomes: -15,275 + 5 / 6

Step 4: Simplify the addition and division. 5 / 6 = 0,8333

The expression becomes: -15,275 + 0,8333

Step 5: Perform the addition. -15,275 + 0,8333 = -14,4417

Therefore, the value of the given expression is approximately -14,4417.
