Question

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

Answer 1

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
 Answer:
 The number of red blood cells is 3571 as great as the number of white blood cells
