Answer 1

Respuesta:

5/2 + 19/7 =  (35+38)/14 = 73/14

7/3 - 4/5 =   (35-12)/15 = 23/15

13/5 - 5/3 =   (39-25)/15 = 14/15

15/4 - 1/5 =  (75-4)/20 = 71/20

7/6 – 1/2 =  (14-6)/12 = 8/12 = 2/3

17/3 – 2/9 =  (153-6)/27 = 147/27 = 49/9

23/9 – 4/3 =  (69-36)/27 = 33/27 = 11/9

5/6 + 8/3 =  (15+48)/18 = 63/18 = 7/2

17/10 + 2/3 =  (51+20)/30 = 71/30

21/8 – 1/6 =  (126-8)/48 = 118/48 = 59/24

3/2 + 7/11 =  (33+14)/22 = 47/22

19/2 + 2/3 =  (57+4)/6 = 61/6

5/3 – 7/10 =  (50-21)/30 = 29/30

7/11 + 5/3 =  (21+55)/33 = 76/33

5/2 + 23/10 =  (50+46)/20 = 96/20 = 24/5

1/2 + 5/3 + 5/8 =  (24+80+30)/48 = 134/48 = 67/24

1/4 + 4/8 + 3/2 =  (2+4+12)/8 = 18/8 = 9/4

1/2 + 11/4 + 4/3 =  (6+33+16)/12 = 55/12

1/2 + 3/2 + 9/7 =  (7+21+18)/14 = 46/14 = 23/7

8/6 + 4/5 + 7/6 = (40+24+35)/30 = 99/30 = 33/10
