I am working on math titles, here I want to reduce the space between colon ":" default it produces before and after space. Could you please suggest me how to rectify this?

MWE:

documentclass{book}



usepackage{amsmath}



begin{document}



$$

DE:AB = 18:6 quad AB:12 = CE:15

$$



end{document}

Just put the colons in groups.

documentclass{book}



usepackage{amsmath}



begin{document}



[

DE{:}AB = 18{:}6 quad AB{:}12 = CE{:}15

]



end{document}

You're using the colon as an operation symbol, which is seldom done in professional mathematics, where the colon usually denotes a relation symbol. However, the colon is commonly found in elementary mathematics.

Here is a visual comparison:

documentclass{book}



usepackage{amsmath}



begin{document}



begin{align}

& DE:AB = 18:6                     && text{too wide} \

& DE{:}AB = 18{:}6                 && text{too tight} \

& DE{,:,}AB = 18{,:,}6         && text{maybe better} \

& DEmathbin{:}AB = 18mathbin{:}6 && text{right, IMO} 

end{align}



end{document}

When you have decided what's best for you, add one of the following definitions (rt is for ‘ratio’, choose a different name if you wish):

newcommand{rt}{{:}}         % for choice 2

newcommand{rt}{{,:,}}     % for choice 3

newcommand{rt}{mathbin{:}} % for choice 4

and input your proportions as

DE rt AB = 18 rt 6

You can redeclare : to be of class mathord. If have to restore the original behaviour, use mathrel{:}.

documentclass{book}



usepackage{amsmath}



DeclareMathSymbol{:}{mathord}{operators}{"3A}



begin{document}



[ DE:AB = 18:6 quad AB:12 = CE:15 ]



end{document}

I propose a command that seems cleaner in my opinion, and that lets you postpone the decision (in case you want to fine tune the output in the future)

newcommand*ratio[1]{cleanratio#1relax}

defcleanratio#1:#2relax{#1mathbin{:}#2}

and then use ratio{DE:AB} = ratio{18:6} = ratio{3:1}. That way if you want to change the output you can (for instance #1,mathord{:},#2, or whatever). If you prefer a cleaner syntax like ratio DE:AB = ratio 18:6 = ratio 3:1 we can implement it.
