How do I to remove a factor of 1

Question

I evaluated

Subscript[ε, 1, 2] = 0.5 Subscript[γ, 1, 2]
2 μ Subscript[ε, 1, 2]

1. μ Subscript[γ, 1, 2]

How do I to remove the factor 1.?

Subscript[ε, 1, 2] = .5 Subscript[γ, 1, 2]

0.5 Subscript[γ, 1, 2]

Rationalize[2 μ Subscript[ε, 1, 2]]

μ Subscript[γ, 1, 2]

% // TeXForm

$\mu \gamma _{1,2}$

Or, use 1/2 instead of 0.5 in your first line:

Subscript[ε, 1, 2] = 1/2 Subscript[γ, 1, 2]

Subscript[γ, 1, 2]/2

2 μ Subscript[ε, 1, 2]

μ Subscript[γ, 1, 2]

thanks, but why we can not directly use 0.5?? – ABCDEMMM Jul 21 '18 at 00:41
@ABCDEMMM, 2 * 0.5 gives 1. and you don't want that. Btw, compare 1 * something with 1. * something – kglr Jul 21 '18 at 00:56
@kglr would you consider this a duplicate of any of the Linked questions? – Mr.Wizard Jul 21 '18 at 03:00
@Mr.Wizard, the last one seems like a duplicate. – kglr Jul 21 '18 at 03:04
Good to know, it is duplicate! thank you @Mr.Wizard. – ABCDEMMM Jul 21 '18 at 23:58
