Answer 1

Ответ:  2.

Объяснение:

1 016.

1)   16 1/2 - 13 7/9 = НОК(2;9) = 18 => 16 9/18 -13 14/18 = (16-13) (9-14)/18 =

= 3 (9-14)/18 = 2 (18+9-14)/18 = 2 13/18;

2)  2 13/18 * 18/33 = (2*18+13)/18 * 18/33 = 49/18 * 18/33 = 49/33;

3)  8/33-1/11 => НОК(33;11)=33 => 8/33-3/33 = 5/33;

4)  2.2*5/33 = 22/10 * 5/33 = (22*5)/(10*33) = 2/2*3 = 2/6 = 1/3;

5)  1/3+2/11 => НОК(3;11)=33=>  11/33+6/33 = 17/33;

6)  49/33 + 17/33 = (49+17)/33 =  66/33 = 2.
