First of all, I hope you have a </head> and <body> between the last
<meta> and the <table>.
For fractions that have entity references in the HTML 4.01
specification, use them in place of the numeric character
references:
¼ for 1/4
½ for 1/2
¾ for 3/4
If the glyphs exist in the viewer's display font, this will work.
For other fractions (and for the above three, if you choose),
create a style that displays the inlines with a smaller font
relative to the current font-size and slightly elevated. For
example:
.fract { font-size: 80%; vertical-align: 20% }
Then use
<p>1 = <span class=fract>1/3</span> + <span class=fract>2/3</span>
This will work even if the viewer does not have fractional glyphs.
Actually, I would probably use <font> in place of <span> because
the effect is supposed to change the size font. I know <font> is
deprecated, but its use here would be mnemonic when I manually edit
an HTML file.
