6/4 can go up to 12/8 which can go up to 18/12

2/12 + 18/12 = 20/12 which reduces to 10/6, 5/3 or 1 2/5
TSO
[tex]\frac{2}{12}+\frac{6}{4}=\frac{2}{12}+\left(\frac{6}{4}\times\frac{3}{3}\right)=\frac{2}{12}+\frac{18}{12} [/tex]

[tex]\to ~ \frac{2}{12}+ \frac{18}{12} = \frac{2 + 18}{12} = \frac{20}{12} = \frac{10}{6} = \frac{5}{3} [/tex]
