810 : 9 = 70 x 2 = 180 : 2 = 30 x 8 = 90 x 9 = 540 : 6 = 60 x 7 = 70 x 9 = 90 x 8 = 420 : 6 = 60 x 3 = 180 : 3 = 60 x 5 = 180 : 8 =

Решение:

Выполним умножение и деление.

1. \( 810 : 9 = 90 \)
2. \( 70 \times 2 = 140 \)
3. \( 180 : 2 = 90 \)
4. \( 30 \times 8 = 240 \)
5. \( 90 \times 9 = 810 \)
6. \( 540 : 6 = 90 \)
7. \( 60 \times 7 = 420 \)
8. \( 70 \times 9 = 630 \)
9. \( 90 \times 8 = 720 \)
10. \( 420 : 6 = 70 \)
11. \( 60 \times 3 = 180 \)
12. \( 180 : 3 = 60 \)
13. \( 60 \times 5 = 300 \)
14. \( 180 : 8 = 22.5 \)

Ответ: 90, 140, 90, 240, 810, 90, 420, 630, 720, 70, 180, 60, 300, 22.5.
