## Why do sky bet not simplify?

This evening I came across this while checking the headlines on the sky sports app.

Apparently, Celtic are 100/30 to reach the group stages of the champions league after going behind. My current footballing knowledge isn’t strong enough to know whether they’re good odd or not, but I do know how odds work.

For those who don’t, the first number is the pay out and the second the stake. In this instance of you place a £30 bet and then Celtic do reach said group stage then you would win £100 (and get your stake back). Any other bet would pay out in the same proportion, so a £15 stake gets £50 and a £60 stake pays £200 etc.

Normally odds are presented in their simplest form, if it can be expressed as a unit ratio (I use this term as I think it’s the closest to what we’re dealing with, I think they should use proper ratio notation in betting shops) and if not 7/2 9/4 etc. In this case the simplest form would be 10/3. Even people with a basic grasp of maths can see there is a common factor of 10 and would find it easy to perform the simplification.

So why have they not? I can only think it is to encourage people, perhaps a little worse for wear, to put £30 on, instead of £3. Or perhaps it’s just a typo. Either way, I find it irksome to see these things left unsimplified!
