Best ResponseYou've already chosen the best response.12=31 so, 1/1*3 = 1/2(2/1*3) = 1/2((31)/3*1) = 1/2[11/3] do this for every term. should i do it in latex, or you got it ?

Best ResponseYou've already chosen the best response.1\[\frac{1}{1 \times 3}=\frac{1}{2} \times \frac{2}{1 \times 3}=\frac{1}{2} \times[\frac{31}{1 \times 3}]=\frac{1}{2} \times[\frac{1}{1 }\frac{1}{ 3}]\] do this for every term.
