Answer 2

It seems like you've provided a series of mathematical expressions. Let's break them down one by one:

1. -3,6-1,6-4,8: (-2) This expression is not clear. It appears to be a combination of numbers separated by commas and a colon, followed by a subtraction operation with (-2). However, it lacks proper formatting or context to understand its meaning.

2. (1 3/7 + 5 3/7-4).(1 1/7) In this expression, we have two mixed numbers: 1 3/7 and 5 3/7. The expression is then multiplied by 1 1/7.

To solve it: 1 3/7 + 5 3/7 = (1 + 5) + (3/7 + 3/7) = 6 + 6/7 = 6 6/7 (6 6/7 - 4) = 2 6/7

Now, we multiply 2 6/7 by 1 1/7: 2 6/7 * 1 1/7 = (2 * 1) + (6/7 * 1) + (2 * 1/7) + (6/7 * 1/7) = 2 + 6/7 + 2/7 + 6/49 = 2 8/49

So, the result is 2 8/49.

3. 0,125.(-6,7).(8) This expression appears to be a multiplication of three numbers: 0.125, -6.7, and 8.

To solve it: 0.125 * (-6.7) * 8 = -0.672

So, the result is approximately -0.672.

4. -3,6.7,4 -3,6.2,6 In this expression, we have two multiplications: -3.6 * 7.4 and -3.6 * 2.6.

To solve it: -3.6 * 7.4 = -26.64 -3.6 * 2.6 = -9.36

So, the results are -26.64 and -9.36.

5. (-5,6+5,6).2,69:134,5 In this expression, we have an addition of two numbers: -5.6 and 5.6, which cancels out to zero. Then, the result is divided by 134.5.

To solve it: (-5.6 + 5.6) = 0 0 / 134.5 = 0

So, the result is 0.
