HTML Entity for Division Slash (∕)
What You'll Learn
How to display the Division Slash (∕) in HTML using hexadecimal, decimal, and CSS entity methods. This glyph is U+2215 (DIVISION SLASH) in the Mathematical Operators block (U+2200–U+22FF) and is used for division in fractions and notation (e.g. 1∕2, 3∕4).
There is no named HTML entity for U+2215. Use ∕, ∕, or \2215 in CSS content. Do not confuse with Division (÷, ÷) or the solidus / (U+002F).

This example demonstrates the Division Slash symbol (∕) using hexadecimal code, decimal HTML code, and a CSS content escape. There is no named HTML entity:
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "\2215";
}
</style>
</head>

🧠 How It Works
Hexadecimal Code
∕ uses the Unicode hexadecimal value 2215 to display the Division Slash symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
∕ uses the decimal Unicode value 8725 to display the same character. This is one of the most commonly used methods.
CSS Entity
\2215 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All three methods produce the Division Slash glyph: ∕. Unicode U+2215 is in Mathematical Operators (U+2200–U+22FF). No named HTML entity exists.
Use Cases
The Division Slash symbol (∕) commonly appears in the following scenarios:
Display 1∕2, 3∕4, and similar fraction notation in math content.
Algebra and formulas using a∕b for quotient-style expressions.
Courses and worksheets teaching fractions with proper Unicode symbols.
16∕9 aspect ratios or year∕month∕day when a dedicated slash is needed.
Technical articles and specs that require the correct division slash character.
Math operator lists and HTML entity guides for science projects.
💡 Best Practices
Do
- Use ∕ for explicit fraction-style division notation
- Use fonts that cover Mathematical Operators (U+2200–U+22FF)
- Pair with text or ARIA (“one half”, “divided by”)
- Pick one numeric style (hex or decimal) per project
- Link to Division (÷) when users need the obelus
Don’t
- Expect a named HTML entity (none exists for U+2215)
- Use
/when ∕ is required for semantic correctness - Confuse ∕ with ÷ (division sign) or ∣ (divides)
- Use CSS escape
\2215inside HTML markup - Mix hex and decimal styles randomly in one file
Key Takeaways

Distinct from / (solidus), ÷ (divide), and ∣ (mid)
❓ Frequently Asked Questions
∕ (hex), ∕ (decimal), or \2215 in CSS content. There is no named HTML entity. All three produce ∕.U+2215 (hex 2215, decimal 8725) in the Mathematical Operators block. Used for division in fractions and mathematical notation./) or division sign (÷).U+2215) is for fraction-style notation (e.g. 3∕4). Division sign (÷, U+00F7, ÷) is the obelus for arithmetic (e.g. 12 ÷ 3 = 4).U+2215) is semantically for division in fractions. Solidus (U+002F, /) is the common forward slash for paths, URLs, and informal division. Use ∕ when the distinction matters.Explore More HTML Entities!
