Every cell is a semi-independent living organism. As such, it needs to eat, excrete, drink, breathe, and reproduce.
Food (glucose and proteins), water, and oxygen are brought into each cell through the blood. Waste products and carbon dioxide are carried out, again through the blood. Without these things, the cell, being stuck in place and unable to go out and forage, will die.

There are 500 white blood cells to every 1000 red blood cells (or you could say there is double the amount of red blood cells). The answer would be 200 red blood cells for every 100 white blood cells.
