Answer 1

1)3441

2)2924

3)-1163

4)3033

5)-7826

Объяснение:

1)

$0.3 \times 10000 = 3000$

$5 \times 100 = 500 - 59 = 441 + 3000 = 3441$

2)

$0.8 \times 10000 = 8000$

$5 \times ( - 1000) - 76 = - 5076 + 8000 = 2924$

3)

$0.7 \times - 1000 = - 7000$

$- 4 \times 100 = - 400 - 63 = - 463 - 700 = - 1163$

4)

$- 0.4 \times 10000 = - 4000$

$- 7 \times ( - 1000) + 33 = 7033 - 4000 = 3033$

5)

$- 0.7 \times 10000 = - 7000$

$- 8 \times 100 - 26 = - 826 - 7000 = 7826$
