27 : 9 + 6 + (4 + 9 + 13) : 7 * 9 =
3 + 6 + (49 + 13) : 7 * 9 =
9 + 62 : 7 * 9 =
9 + 8,85 * 9 =
9 + 79,65 = 88,65
a) x - 53 = 375
x = 375 + 53
x = 428
б) x : 8 = 10
x = 10 * 8
x = 80
Выражение:
(n + 6) / n
(896 : 16) : (896 : 16) =
56 : 56 = 1
Ответ: 68, 387, 1400, 250, 60, 88.65, 428, 80, (n + 6) / n, 1
