ответ: 10 1/90
5 1/3 : 6 2/5 + (12 : 3 3/5 - 2/3) * 2/3 + 7 2/5 = 10 1/90
1) 12 : 3 3/5 = 12 : 18/5 = 12 * 5/18 = 10/3
2) 10/3 - 2/3 = 8/3
3) 5 1/3 : 6 2/5 = 16/3 : 32/5 = 16/3 * 5/32 = 5/6
4) 8/3 * 2/3 = 16/9
5) 5/6 + 16/9 = 15/18 + 32/18 = 47/18
6) 47/18 + 7 2/5 = 47/18 + 37/5 = 235/90 + 666/90 = 901/90 = 10 1/90
