= (1\8 + 25\54 : 5\9 + 3\11) *11\5 = (1\6+5\6 +3\11) * 11\5 = (11\11 + 3\11 * 11\5 = 14\11 * 11\5 = 14\5 = 2.8

Пошаговое объяснение:
5/72 : 5/96 = 5/72 * 96/5=96/72=4/3
1:2/3 = 1 * 3/2 = 3/2 = 1 1/2
2 1/3 : 1 1/4 = 7/3 : 5/4 = 7/3 * 4/5 = 28/15 = 1 13/15
16/27 : 2/9 = 16/27 * 9 /2 = 8/3 = 2 2/3
2 : 1/4 = 2* 4/1 = 8
8/3 : 2/3 = 8/3 * 3/2 = 8/2 = 4
