Ответ:
2 8/9
Пошаговое объяснение:
11 2\9 - (2 4/9 + 5 8/9) = 2 8/9
1) 2 4/9 + 5 8/9 = 8 3/9
2) 11 2/9 - 8 3/9 = 101/9 - 75/9 = 26/9 = 2 8/9
две целых восемь девятых
1)2 4/9 + 5 8/9 = 7 + 4/9 + 8/9 = 7 + 4 + 8/9 = 7 +12/9 = 7 + 4 · 3/3 · 3 = 7 + 4/3 = 8 1/3
2)11 2/9 - 8 1/3 = 101/ 9 - 25/ 3 = 101 /9 - 75/ 9 = 101 - 75/ 9 = 26/ 9 = 2 8/9
