40 . (18 : 9) = 5 . 8 : 20 = 30 . (24 : 8) = 10 . 8 : 40 = 20 . (24 : 6) = 90 . (5 : 6) =

Решение:

1. \( 40 0 (18 : 9) = 40 0 2 = 80 \)
2. \( 5 0 8 : 20 = 40 : 20 = 2 \)
3. \( 30 0 (24 : 8) = 30 0 3 = 90 \)
4. \( 10 0 8 : 40 = 80 : 40 = 2 \)
5. \( 20 0 (24 : 6) = 20 0 4 = 80 \)
6. \( 90 0 (5 : 6) = 90 0 \frac{5}{6} = \frac{90 0 5}{6} = 15 0 5 = 75 \)

Ответ: 80; 2; 90; 2; 80; 75.
