Type a price in any format — decimal, fractional, American or as a percentage — and see it in all the others, plus what it implies and what GH₵1,000 returns.
1.85 means GH₵85 profit on every GH₵100 staked, or GH₵1,850 returned on GH₵1,000. The implied chance is 1 ÷ 1.85 = 54.05%.
Fractional odds show profit only. 5/2 means you win GH₵5 for every GH₵2 staked, so a GH₵10 stake returns GH₵35 — which is 3.50 in decimal.
No. A better price is only value if it is higher than the true chance of the outcome. The implied probability column shows what the book is claiming.
