Answer 1

-9.3 + 10,2 - 12,6 +10,6 -12 + 2
________________________    =  -11,1/12
                        12

Answer 2

1) -3 1/4+5 3/4=2 1/2
2) 5 1/6+1/6=5 1/3
3) 2 1/2-2 1/2=0
4) 0-1=-1

Answer 3

To simplify the given expression, follow these steps:

Step 1: Find a common denominator for all the fractions involved. Step 2: Perform the arithmetic operations.

Here's the step-by-step solution:

Step 1: The common denominator for the fractions 4, 6, and 2 is 12. So, rewrite each fraction with a denominator of 12.

-3.1/4 = (-3.1 * 3) / (4 * 3) = -9.3/12 5.1/6 = (5.1 * 2) / (6 * 2) = 10.2/12 2.1/2 = (2.1 * 6) / (2 * 6) = 12.6/12 5.3/4 = (5.3 * 3) / (4 * 3) = 15.9/12 1/6 = (1 * 2) / (6 * 2) = 2/12

Step 2: Perform the arithmetic operations:

-9.3/12 + 10.2/12 - 12.6/12 + 15.9/12 - 1 + 2/12

Now, add the fractions:

(-9.3 + 10.2 - 12.6 + 15.9) / 12 - 1 + 2/12

Now, perform the addition:

(4.2) / 12 - 1 + 2/12

Now, perform the division:

0.35 - 1 + 2/12

Now, perform the subtraction:

0.35 - 0.91667

Now, calculate the result:

-0.56667

So, the simplified value of the expression is approximately -0.56667.
