Direction cosine and ratio of line

Can be the direction cosines of a line?

If the direction cosine of a line are , then,

If l,m,n are direction cosines of the line then -l,-m,-n can be: a) only direction ratios of the line b) only direction cosines of the line c) direction cosines and direction ratios of the line d) neither direction cosines nor direction ratios of the line

If a line has direction cosines , then find the direction ratios.

If the direction ratio of a line is 1,-2,2 Then what are the direction cosines of the line

If a line has direction ratios , then what are its direction cosines?
