1)5/18*26/15=26/54
2)26/54+1/9*6=26/54+6/54=32/54
3)32/54*27/16=2/1*1/2=2/2=1
ответ:1
(5/18 * 1 11/15 + 1/9) * 1 11/16 =
= (5/18 * 26/15 + 1/9) * 1 11/16 =
= (13/27 + 3/27) * 1 11/16 =
= 16/27 * 27/16 = 1,
или (по действиям):
1) 5/18 * 1 11/15 = 5/18 * 26/15 = 13/27,
2) 13/27 + 1/9 = 13/27 + 3/27 = 16/27,
3) 16/27 * 1 11/16 = 16/27 * 27/16 = 1
