Question

(2,4×7/6-5 1/3) ÷(-19,2-4 1/3-1,8)

Answer 1

Ответ:

Пошаговое объяснение:

2,4*7/6=12/5*7/6=14/5=2 4/5

2 4/5-5 1/3=2 12/15-5 5/15=-2 8/15

-19,2-1,8=-21

-21-4 1/3=-25 1/3

-2 8/15:(-25 1/3)=-38/15*(-3/76)=1/10=0,1

Answer 2

To solve this expression, follow the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction). Here's the step-by-step solution:

1. First, simplify the expressions within parentheses: (2,4×7/6 - 5 1/3) ÷ (-19.2 - 4 1/3 - 1.8)

   Start with the multiplication within the first set of parentheses: 2.4 × 7/6 = 2.8

   Now we have: (2.8 - 5 1/3) ÷ (-19.2 - 4 1/3 - 1.8)

2. Next, subtract the mixed numbers (5 1/3) within the first set of parentheses: 2.8 - 5 1/3 = -2.5

   Now we have: (-2.5) ÷ (-19.2 - 4 1/3 - 1.8)

3. Subtract the mixed number (4 1/3) within the second set of parentheses: -19.2 - 4 1/3 = -19.2 - 13/3 = -19.2 - 4.33 ≈ -23.53 (rounded to two decimal places)

   Now we have: (-2.5) ÷ (-23.53 - 1.8)

4. Subtract 1.8 from -23.53: -23.53 - 1.8 = -25.33

   Now we have: (-2.5) ÷ (-25.33)

5. Finally, divide -2.5 by -25.33: (-2.5) ÷ (-25.33) ≈ 0.0988 (rounded to four decimal places)

So, the final result is approximately 0.0988.
