Explicación paso a paso:

1) 2 + 3/4 - (3 3/10 - 2) = 28/10 = 14/5

2) 3 1/5 : 1 3/11= 16/5 / 14/11= 16/11 . 14/11 = 176/60 = 88/35

3) (1/2 / 3/5)/ 5/6 = (1/2 . 5/3) = (5/6)/ 5/6 = 5/6 / 5/6 = 5/6 . 5/6 = 30/30 = 1

4) 15 -(25/6 - 7/2) + (4/18 . 8/5) = 15 -(2/3)+(16/45) = 1/15 - 2/3 + 16/45 =

    -3/5 + 16/45 = 43/45

5) ( 3 - 1/4) / (2 - 2/6) = (1/12) / (1/6) = 1/2 . 6/1 = 6/2 = 3/1 = 3

6) (24/3) / (8/9 / 1/6) = (24/3) / (8/9 . 6/1) = (24/3) / (48/9) = (8/1) / (16/3) =

   8/1 . 3/16 = 24/16 = 3/2

7) (1 + 2/21) / (2 8/9 - 1 5/8) = (23/21) / (91/72) = 2093/1512 = 299/216

8) 14/39 .(13/7 / 3/5) = 14/39 .(13/7 . 5/3) = 14/39 .(65/21) = 910/819 = 10/9
