Yes, I could assure you that it's conventional (ie. it is a
convention / habit) to use same font size in fraction as well as in non
fraction. In this fraction
y²
x = --
z
the default behaviour of LyX (and LaTeX?) is to use smaller font for 'y'
and 'z', and an even smaller one for '2', but usually, 'x', 'y' and 'z'
should have the same size.
You could check this by looking at any scientific books, reviews,
letter or articles. If you like, here are some English references at my
disposition to persuade you:

438359 2 (For ex, page 347)
* Further Pure Mathematics; Bostock et al.; ELBS; 1987; ISBN 0 85950 519

(any page)
* Introduction to Quantum Mechanics; Bransden et al.; Longman Scientific
& Technical; 1992; ISBN 0-582-44498-5 (any page)
* A numerical library in C for Scientists and Engineers; Lau; CRC Press;
1995; ISBN 0-8493-7376-X (eg page 286)
And even in this old article dated in 1962:
Weinberg S., Eikonal Method in Magnetohydrodynamics, The Physical Review,
Vol 126, No 6 (1962), page 1899
And of course, it's the same in French books/articles.

I suppose you mean in my .lyx file, right? Well, I put these two
lines at the beginning of the file and before "\layout Standard" using a
text editor. I then open it using LyX but I get this message:
LyX: Unknown token `\usepackage{amsmath}'. Inserting as text. [around
line 25 of file ~/doc/Parabole.lyx]
LyX: Unknown token `\let'. Inserting as text. [around line 25 of file
~/doc/Parabole.lyx]
LyX: Unknown token `\frac='. Inserting as text. [around line 25 of file
~/doc/Parabole.lyx]
LyX: Unknown token `\dfrac'. Inserting as text. [around line 26 of file
~/doc/Parabole.lyx]
