hey

can some 1 show me how to work out the odds in fraction form if you know the percent, for example AA V AK the percentages of AA winning are 92% and 8% for AK to win,  how do i convert them if you can? Thanks

[ItsMrAlex2u]

92/100 or 23/25
and
8/100 or 2/25

hi timber, I have some conversion tables somewhere but cant lay my hands on them at the mo, if you search the web for summat like odds conversion charts you might come up with summat, sorry I couldnt be more helpful at the mo but I am off out 5 mins ago.

cheers

As near as it needs to be, try this. If you are 8% to win, divide 100 by 8, = 12 (ish), & there's the answer - 12%.

With bigger percentages, try this. A 33% shot is 2/1 - 100 divided by 33 is 3, we will win once & lose twice every 3 goes. So, a 2/1 shot.

50% is even money, because 50 goes into 100 twice, & we win once, & lose once - so it's Evens.

So 8% becomes 12%....?

I did misread the original post though. Thought it was just asking about converting to fractions, not odds.

Odds and fractions - not quite the same thing (although people do sometimes use them interchangeably)

Odds are ratios.

So 3:1 means 3 of something for one of something. - therefore there are 4 things in total.

Odds to fractions
What you have on one side 'over' the sum of both sides.

so 3/4 and 1/4

Percentages are fractions
But they are always over a 100, so you don't need to write the bottom bit. So  3/4 = 75/100, but you don't need the "/100" for a percentage - instead it's 75%

Going back the other way - you just reverse it, but obviously any number of 'awkward' numbers exist in percentages which don't easily convert back to fractions or odds.

Unless you need an exact number a bit of rounding will usually give you a much easier result.

e.g. 92% = 92/100 = 47/50

But if you say 92% is approximately 90% = 90/100 = 9/10 = 9:1
Much easier.

And even easier if you just avoid odds and stick to fractions or percentages in my opinion.


EDIT: I know this is a bit in note form, but I'm hungry so I can't write any better until I've eaten

Oops, mistype. 12/1.

Being on the uneducated side of poker maths is there any courses/seminars that make it easy to comprehend??

GCSE maths!  If they used proper examples and poker, then I'm sure many more people would understand fractions and percentages.

always wondered and am always fascinated by  darts players,they must be maths geniuses...they have their outs worked out in seconds..


does your professional poker player have all the odds imprinted in their head when figuring out their outs..

cos i sure dont

lol

1st I have to work out the odds then discount any if applicable,then try and get a read..the make a decision...live or online...


just wondered if maths skills in poker become intuitive given time??

i think im good at maths but decisions maths based for me are never instantaneous

All maths skills become intuitive over time if they're practised enough.

I worked for 5 years as an odds compiler and these percentages become second nature the more you use them. I would say its the same for poker too, I sat down with an out chart and remembered turn and river odds for each number of outs. Now I am no maths genius so it was literally a case of learning and testing myself until they all became second nature too.

As for darts players i think its just the same principal, you learn a set of 'outs' for each number and they just stay in there, I know as a kid my maths improved a lot by watching darts.

You only need 'odds' when explaining to someone who doesn't percentages. Stick to % it's the future
