Answer 2

To solve this expression, we need to follow the order of operations, also known as PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction), and simplify each operation one by one.

Starting with the parentheses, we can simplify the division first:

11,2 ÷ 9 1/3 = (11 × 3 + 2) ÷ (9 × 3 + 1) = 35/28

So, the expression becomes:

13 2/5 - 35/28 × (-5/12)

Next, we need to simplify the multiplication:

35/28 × (-5/12) = -(35 × 5)/(28 × 12) = -35/67

So, the expression becomes:

13 2/5 - (-35/67)

Now, we can simplify the subtraction:

13 2/5 + 35/67 = (13 × 67 + 2 × 67 + 35) / 67 = 904/67

Therefore, the final answer is:

(13 2/5 - 11,2 ÷ 9 1/3)×(-5/12) = -904/67 × 5/12 = -4520/804 = -565/100.
