Answer 2

Explicación paso a paso:

1/2 + 7/8 = (1*8 + 2*7)/(2*8) = 11/8.

1/3 + 3/4 = (1*4 + 3*3)/(3*4) = 13/12.

7/9 + 1/2 = (7*2 + 9*1)/(2*9) = 23/18.

2/5 + 1/6 = (2*6 + 5*1)/(5*6) = 17/30.

15/6 + 2/3 = (15*3 + 6*2)/(6*3) = 57/18 = 19/6.

20/7 + 1/3 = (20*3 + 7*1)/(7*3) = 67/21.

1/8 + 5/6 = (1*6 + 8 *5)/(8 * 6) = 46/48 = 23/24.
