Boa noite
a = 1/3 = 2/6
b = 1/6
soma S = 2/6 + 1/6 = 3/6 = 1/2
media m = S/2 = (1/2)/2 = 1/4 = 0.25
a = 3/5 = 12/20
b = 13/4 = 65/20
c = 1/2 = 10/20
soma S = (12 + 65 + 10)/20 = 87/20
media m = S/3 = 87/60 = 29/20 = 1.45
a = 1/3 = 2/6
b = 1/6
soma S = 2/6 + 1/6 = 3/6 = 1/2
media m = S/2 = (1/2)/2 = 1/4 = 0.25
a = 3/5 = 12/20
b = 13/4 = 65/20
c = 1/2 = 10/20
soma S = (12 + 65 + 10)/20 = 87/20
media m = S/3 = 87/60 = 29/20 = 1.45
