People sometimes do have eating disorder. Bulimics, when confronted will not accept help, but anorexics will accept help is a false statement.
Bulimia is simply known as a psychological eating disorder where a person often consume a large quantity of food at once. They often do not have any measure control over their eating. Thereafter, they try foolish ways to lose weight such as Vomiting
, Fasting etc.
Anorexia is simply known as when an individual have a great fear of gaining weight. Individuals who have this disorder often eat so little that they become very thin.
Conclusively, confronting people who have disorder is done in a good way because they may deny it at first but when you talk to them and they open up, they will go for treatment.
It should be easy, I don't know how to really explain this but it think it's 33.2% divided by the other number or so, if this is wrong just search up a caculator.
