Answer 1

Ответ:

1. -4  7/18

Пошаговое объяснение:

 1. 5/9 + 3 * (15, 45 : 1,5 - 11,8) = -4  7/18 ​

1) 15,45 : 1,5 = 10,3     2) 10,3 - 11,8 = -1,5    3) 3 * (-1,5) = -4,5     4)  5/9 + (-4,5) = 5/9 + (-4  5/10) =  -4  7/18

Answer 2

Let's break down the expression step by step:

1. First, perform the division inside the parentheses: 15, 45 ÷ 1,5 = 10

2. Next, subtract 11,8 from the result: 10 - 11.8 = -1.8

3. Now, multiply 3 by the result from step 2: 3 * (-1.8) = -5.4

4. Finally, add 5/9 to the result from step 3: -5.4 + 5/9

To add a fraction to a decimal, you need to convert the fraction to a decimal or vice versa. Let's convert 5/9 to a decimal:

5/9 is approximately equal to 0.5556 (rounded to four decimal places).

Now, add -5.4 to 0.5556:

-5.4 + 0.5556 ≈ -4.8444

So, the result is approximately -4.8444.
