📐 What Are Fractional Odds?
Fractional odds are the traditional UK betting format. You’ll often see them in this form:
- 5/1 (“five to one”)
- 10/3 (“ten to three”)
- 6/4 (“six to four”)
How to read them:
- The first number = potential profit
- The second number = amount staked
So 5/1 means:
- For every £1 you bet, you win £5 (plus your stake back)
Example:
- You bet £10 at 5/1
- Return: £50 profit + £10 stake = £60 total

🧮 What Are Decimal Odds?
Decimal odds are more common in Europe and online sportsbooks. They look like this:
- 6.00
- 3.33
- 1.50
How to read them:
- Decimal odds = total return per £1 staked
So 6.00 means:
- You get £6 total back for every £1 bet (£5 profit + £1 stake)
Example:
- You bet £10 at 6.00
- Return: £60 (including stake)
