    if an object is 10 units long, then 1/10th of it is 1 unit long if an object is 3 units long, then 1/3rd of it is 1 unit long if an object is 1/5 units long, then 5/1ths of it is 1 unit long if an object is L units long, then 1/Lth of it is 1 unit long

    If, \(\Large\color{black}{ \displaystyle \vec{v}= \langle a,b\rangle }\) Then, the unit vector in direction of v is, \(\Large\color{black}{ \displaystyle \langle \frac{a}{\left|\vec{v}\right|},{~}\frac{b}{\left|\vec{v}\right|}\rangle }\) (divide each component by the vector's magnitude.
