Fraction 2 by 3 (⅔) is the Unicode character at U+2154 in Number Forms. Official name: VULGAR FRACTION TWO THIRDS. It is one precomposed fraction glyph — not the three characters 2/3.
Remember
Character ⅔
Unicode U+2154
Named entity ⅔
Hex entity ⅔
Decimal ⅔
CSS escape \2154
Meaning vulgar fraction two thirds (2/3)
Not the same 2/3 (three chars) · ⅓ (1/3) · ⅖ (2/5)
Prefer ⅔ in HTML for readable markup. You can also use ⅔, ⅔, or type ⅔ in a UTF-8 document.

Math: 3 × ⅔ = 2
How It Works
1. Named:⅔ is the HTML5 name for U+2154 → ⅔.
2. Hex:⅔ inserts the same code point by hexadecimal value.
3. Decimal: same code point as 8532 → ⅔. Same visual as named/hex.
4. CSS: use \2154 in content (not an HTML entity). #point::after appends ⅔.
5. Typed: paste ⅔ in a UTF-8 document when you need the two-thirds glyph as one character.
Pitfalls & Tips
Common mistakes when working with fraction 2 by 3.
Name
Prefer ⅔
The named entity is clear and standard. Avoid inventing names like &twothirds;.
2/3
Not three characters
Typing 2/3 creates three code points. ⅔ is one Number Forms character.
⅓
Not one third
One third is ⅓ (U+2153, ⅓). Use it when you mean 1/3, not 2/3.
Font
Font coverage
Some fonts omit Number Forms fractions. If ⅔ is missing, fall back to 2/3 or a font with Number Forms coverage.
CSS vs HTML
Do not mix escapes
\2154 belongs in CSS strings. ⅔ / ⅔ / ⅔ belong in HTML.

Add accessible text
Screen readers may not announce ⅔ clearly. Prefer aria-label="two thirds" or nearby prose when the fraction carries meaning.
Semicolon
End references
Always finish entities with ; — write ⅔, not &frac23.
