Пошаговое объяснение:
(1)
((13-2 2\3*1 1\4 * 9\10)*(2\3:4\9-0,5): 3 1\7): 3 2\11 = 1
1) 2 2/3 * 1 1/4 = 8/3 * 5/4 = 10/3
2) 10/3 * 9/10 = 3
3) 13 - 3 = 10
4) 2/3 : 4/9 = 2/3 * 9/4 = 3/2 = 1,5
5) 1,5 - 0,5 = 1
6) 10 * 1 = 10
7) 10 : 3 1/7 = 10 : 22/7 = 10 * 7/22 = 35/11
8) 35/11 : 3 2/11 = 35/11 : 35/11 = 1
ответ: 1
(2)
(( 2 1\4 * 1 1\9* 4\15 - 1\3)*(9- 6\7:3\14)+ 2 1\3)* 17 1\4 = 69
1) 2 1/4 * 1 1/9 = 9/4 * 10/9 = 5/2
2) 5/2 * 4/15 = 2/3
3) 2/3 - 1/3 = 1/3
4) 6/7 : 3/14 = 6/7 * 14/3 = 4
5) 9 - 4 = 5
6) 1/3 * 5 = 5/3 = 1 2/3
7) 1 2/3 + 2 1/3 = 4
8) 4 * 17 1/4 = 4 * 69/4 = 69
ответ: 69
x=512+302 x=814 814-512=302
