jika x= 1+5/12 dan y= 1+6/13 maka... a. x > y b. x < y c. x = y d. x + y = 0 e. x - 2y > 0

a, b, dan c 1 + 5/12 ><=1 + 6/13
5/12 + 6/13 ><= 1 + 1
65/156 + 72/156 ><= 2
137/156 ><= 2
d 1 + 5/12 + 1 + 6/13 = 0
6/12 + 7/13 = 0
78/156 + 84/156 = 0
162/156 = 0
1 6/156 = 0
e 1 + 5/12 - 2(1 + 6/13) = 0
6/12 - 2 - 12/26 = 0
Yg e bingung caranya
