Пошаговое объяснение:

(-3 1/4+2 1/6)= -1 1/12

-1 1/12*(-2 2/11)=2 4/11

2 4/11+7/11=2 11/11=3

Answer 3

To solve this expression, we can break it down into smaller steps:

Step 1: Add the mixed numbers -3 1/4 and 2 1/6:

-3 1/4 + 2 1/6

First, find a common denominator for 4 and 6, which is 12. Then convert both fractions to have a denominator of 12:

-3 * 12/4 + 2 * 12/6 = -36/4 + 24/6

Now, simplify each fraction:

-36/4 = -9 24/6 = 4

So, the expression becomes:

-9 + 4

Step 2: Add -9 and 4:

-9 + 4 = -5

Now, we have:

-5 * (-2 2/11) + 7/11

Step 3: Multiply -5 by -2 2/11:

To multiply a mixed number by a whole number, you can first convert the mixed number to an improper fraction and then multiply:

-2 2/11 = -24/11 (improper fraction)

Now, multiply:

-5 * (-24/11) = 120/11

Step 4: Add 7/11 to 120/11:

(120/11) + (7/11) = (120 + 7)/11 = 127/11

So, the final result of the expression is 127/11.
