trên tia Ox có OM<ON(3<6) nên M sẽ nằm giữa O và N =>OM+MN=ON        (1)

thay ON= 6 cm ;OM= 3 cm ,ta co :

3+MN=6

MN=6-3=3(cm)

=>OM=MN(=3cm)         (2)

từ (1) và ( 2) => M là trung điểm của ON 

vì K là trung điểm của OE 

=>EK=KO=OE/2=4/2=2(cm)

vì K thuộc vào tia đối của tia Ox còn M thuộc vào tia O x nên OK  và OM cũng là 2 tia đối nhau và O sẽ nằm giữa=>KO+OM=KM

thay OM=3 cm ;KO=2 cm ,ta co :

3+2=KN

KN=3+2=5(cm)
