The average adult human has approximately 2.5 x 10 ^ 13 red blood cells + 7 x 10 ^ 9 white blood cells about how many times as great is the number of red blood cells than the number of white blood cells

To solve this problem, what we must do is use the following equation:
 N = (red blood cells) / (white blood cells)
 Substituting values we have:
 N = (2.5 * 10 ^ 13) / (7 * 10 ^ 9)
 N = 3571.428571
 Nearest whole number:
 N = 3571
 
 The number of red blood cells is 3571 as great as the number of white blood cells
