Answer 2

Explicación paso a paso:

5/7 + 3/9 =  (45+21)/63 = 66/63

8/6 + 3/6 + 1 2/2 =  8/6 + 3/6 + 4/2 = 8/6 + 3/6 + 12/6 = 23/6

3/6 + 1 + 5/5 + 8/8 =   3/6 + 1 + 1 + 1 = 3/6 + 6/6 + 6/6 + 6/6 = 21/6

3/12 + 8/4 =  3/12 + 24/12 = 27/12

3/6 + 5/9 =  9/18 + 10/18 = 19/18

9/2 + 3/7 =  63/14 + 6/14 = 69/14

7/6 + 2/5 = 35/30 + 12/30 = 47/30

merezco la mejor respuesta, esta fue una tarea completa :)
