Question

14,6*(6,6-7,1) (5/6+2/9):0,5

Answer 1

14,6*(6,6-7,1)=14,6*(-0,5)=-7,3

(5/6+2/9):0,5=(15/18+4/18):5/10=19/18:5/10=19/18*10/5=19/18*2=19/9=2 1/9

Answer 2

14,6*(6,6-7,1)=
6,6-7,1=-0,5
14,6*(-0,5)=-7,3

Тут мы делим 6 на 5, если будем делить наоборот то получится слишком много чисел как 0,833333 так что будем делить наоборот

(5/6+2/9):0,5=
1,2+0,5=5,7
5,7:0,5=11,4
Как то так.-. Пойдёт? ._.

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break it down step by step:

1. First, calculate the expression inside the parentheses: 6.6 - 7.1 = -0.5

2. Next, calculate the expression inside the second set of parentheses: (5/6 + 2/9) = (15/18 + 4/18) = 19/18

3. Now, multiply the results of steps 1 and 2: 14.6 * (-0.5) * (19/18)

4. Finally, divide the result from step 3 by 0.5: (14.6 * (-0.5) * (19/18)) / 0.5

Now, perform the calculations:

• Step 1: -0.5
• Step 2: 19/18
• Step 3: 14.6 * (-0.5) * (19/18) = -7.7 * (19/18)
• Step 4: (-7.7 * (19/18)) / 0.5

Now, calculate the final result:

= (-7.7 * 19/18) / 0.5 = (-146.3 / 18) / 0.5 = -8.127777777777778 / 0.5 = -16.255555555555556

So, the final result is approximately -16.26.
