when u go to a monster on the tip it beastiary it has a ratio number. what is that ratio representing?

The 'How to use the Bestiary' explains this, it can be found here (or by clicking How to use the Bestiary at the upper-right on any monster's page). The information's also quoted below. :)

 

Ratio

The ratio is the monster's life points divided by ten, then by its level. It will help you to determine how efficient it is to train on. The higher the number the better the monster is for training. For example, the Ice Giant (level 53) has 700 life points. 700/10/53 = 1.32. The Ogre (level 53), on the other hand, has 600 life points. 600/10/53 = 1.13. So by purely level to life points it would be better to train on the Ice Giant, but remember you must take into account the average damage and the defensive capabilities of the monsters (something pure numbers can't tell you).
