Can two skew lines intersect in exactly one point?
always
When are two lines in intersecting planes skew?
Each line can either intersect the edge which is common to the two planes at some point or be parallel to it. If the two lines intersect the edge, but at different points, then the lines are skew. If only one of the lines intersects the edge, then again the lines are skew. If neither of them intersect, then the two lines are parallel to the same edge and so they are parallel to one another so not skew.
How many planes can pass through a pair of skew lines?
One if the two lines meet, none otherwise. But skew lines do not lie in the same plane, by definition.
Can a whole number be an ratio?
Yes it is esssentially that number to one ratio five written as a ratio would be a five to one ratio
