Explicación paso a paso:
11. 30 + 15/50 = 45/50 = 9/10
12. 117 + 78/ 338 = 195/338
13. 3/7 - 1/4 = 12 - 7/28 = 5/28
14. 5/8 - 1/3 = 15 - 8/24 = 7/24
15. 7/8+3/16 = 112+24/128 = 136/128 = 68/64 = 34/32
= 17/16 = 1 1/16
16. - 16 - 35/40 = - 51 /40
17. 24-20/32 = 4/32 = 1/8
18. 5/7 - 10/21 = 105-70/147 = 35/147
19. -8+6/16 = -2/16 = -1/8
20. -24 + 21/36 = -3/36 = -1/12
21. 7/5 -1/3 = 21-5/15 = 16/15 = 1 1/15
22. 7/8 + 97/24 = 168 + 776/192 = 944/192 = 472/96 =
236/48 = 118/24 = 59/12
23. - 20/3 - 8/9 = - 180 - 24 / 27 = - 204/27
24. 76/30 - 7/15 = 1140 - 210/450 = 929/450
25. -25/6 - 137/18 = - 450 - 822/108 = - 1272/108 =
- 636/54 = - 318/27
26. 7/2 + 22/3 = 21 + 44/6 = 65/6
27. - 155/8 + 19/4 = - 620 + 152/32 = - 468/32 = - 234/16
= - 117/8
28. - 17/5 + 18/7 = - 119 + 90/ 35 = - 29/35
