Answer 2

Ответ:

3 целых 1/20

Пошаговое объяснение:

1. 8-7,25= 55/100= 11/20
2. 16,32*11/20= 17,952/2000= 1122/125= 8 целых 122/125
3. 9,84-8 целых 122/125= 432/500= 108/125
4. 108/125+2,186= 3050/1000=61/20=3 целых 1/20

Answer 3

To calculate the expression:

9.84 - 16.32 * (8 - 7.45) + 2.186

Follow the order of operations (PEMDAS/BODMAS):

1. First, calculate the value inside the parentheses:

8 - 7.45 = 0.55

2. Next, multiply 16.32 by the result from step 1:

16.32 * 0.55 = 8.976

3. Now, subtract the result from step 2 from 9.84:

9.84 - 8.976 = 0.864

4. Finally, add 2.186 to the result from step 3:

0.864 + 2.186 = 3.05

So, the final result is 3.05.
