Question

me gustaría que si me pueden ayudar

Answer 1

1) 9/2 + 13/2 - (4/2 + 1/2) = 22/2 - 5/2 = 17/2

2) 8/3 - (7/3 - 4/3) + 12/3 = 20/3 - 3/3 = 17/3

3) 9/7 - 5/7 + (3/7 - 1/7) + 3/7 = 7/7 + 2/7 = 5/7

4) 14/11 - (3/11 + 1/11 + 2/11) + 8/11 = 22/11 - 6/11 = 16/11

5) 21/13 - (4/13 - 1/13) + 11/13 + 2/13 = 23/13 - 3/13 = 20/13

6) 1/2 + 1/3 - (1/4 + 1/5) = (3+2)/6 - (4+5)/20 = 5/6 - 9/20 = (100-54)/120 = 46/120 = 23/60

7) 1/3 + 1/6 + (1/4 - 1/8) = (6+3)/18 + (8-4)/32 = 9/18 + 4/32 = 1/2 + 1/8 = (8+2)/16 = 10/16 = 5/8

8) 1/5 + 4/3 + 1/2 = (6+40+15)/30 = 61/30

9) 2/3 + 1/9 + 3/5 = (30+5+27)/45 = 62/45

10) 4/7 + 2/4 + 1/8 = (32+28+7)/56 = 67/56

11) 3/2 + 1/5 + 1/10 = (15+2+1)/10 = 18/10 = 9/5

12) 3/8 + 1/4 + 3/16 = (6+4+3)/16 = 13/16

13) 4/5 - 1/7 = (28-5)/35 = 23/35

14) 3/10 - 1/12 = (36-10)/120 = 26/120 = 13/60
