Question

5) (48,316 - 19,83) 20; 6) (15,078,9) - 30; 7) (2-0,7). 50; 8) (39,8 + 116,7) 12. ●​

Answer 1

Ответ:

5) (48,316-19,83)20=28,486*20=569,72;

7) (2-0,7)50=1,3*50=65;

8) (39,8+116,7)12=156,5*12=1878.

Answer 2

To calculate the given expressions, I will perform the operations as follows:

5. (48,316 - 19,830) ÷ 20

48,316 - 19,830 = 28,486 28,486 ÷ 20 = 1,424.3

Therefore, the result of expression 5) is approximately 1,424.3.

6. (15,078.9) - 30

15,078.9 - 30 = 15,048.9

Therefore, the result of expression 6) is 15,048.9.

7. (2 - 0.7) × 50

2 - 0.7 = 1.3 1.3 × 50 = 65

Therefore, the result of expression 7) is 65.

8. (39.8 + 116.7) ÷ 12

39.8 + 116.7 = 156.5 156.5 ÷ 12 = 13.04

Therefore, the result of expression 8) is approximately 13.04.

In summary: 5) Result: approximately 1,424.3

6. Result: 15,048.9
7. Result: 65
8. Result: approximately 13.04
