A runway names "27-09" can be approached for landing by heading 270 or 090 on the compass, or, in layman's language, the runway can be used by lining up with the runway at an appropriate descent and then heading 270 or heading 090 as it runs exactly east-and-west.

Airport runways are designated by a two digit number equal to their magnetic heading in degrees divided by ten and rounded. A runway with a double designation can be approached in either direction. Thus a runway designated 09/27 runs east and west relative to magnetic north.

The numbers represent the compass headings, one for each approach direction, so the numbers are always 180 degrees apart.
For simplicity, the last zero is dropped, so your example is for a runway running exactly east-west at 270 degrees or 090 degrees, with 000 degrees being due north.

RUNWAYS ARE NAMED ACCORDING TO THEIR LOCATION. aS YOU LOOK AT A COMPASS AND YOU SEE CERTAIN NUMBER DEGREES SOUTH OR WEST AND THE RUNWAY IS NAMED AFTER ITS LOCATION. wHEN A PLANE IS READY TO LAND AND THE PILOT HEARS WHICH RUNWAY TO USE,ALL hE HAS TO DO IS LINE THE PLANE UP WITH THE COMPASS.

because those are the headings on the compas that the poin in r09 090degrees r27 270 degrees it makes spacial orientation easier
