T = 1/3 + 1/12 + 1/30

T = 20/60 + 5/60 + 2/60

T = 27/60

T = 9/20

U = 7/6 + 5/12 + 3/16

U = 56/48 + 20/48 + 9/48

U = 85/48

V = 1/2 + 5/4 + 4/5

V = 10/20 + 25/20 + 16/20

V = 51/20

W = 1/4 + 1/8 - 1/16

W = 4/16 + 2/16 - 1/16

W = 6/16 - 1/16

W = 5/16

Y = 4/9 + 8/15 - 2/3

Y = 20/45 + 24/45 - 30/45

Y = 44/45 - 30/45

Y = 14/45

Z = 1/6 - 8/27 - 7/18

Z = 9/54 - 16/54 - 21/54

Z = -28/54

Z = -14/27
