Answer:
6.63 x 10^2 times
Explanation:
The number of times greater the number of red blood cells is than white blood cells is the result of the ratio of the number of red blood cells to the number of white blood cells.
Given that there are approximately 2.6x10^13 red blood cells and 3.92x10^10 white blood cells, the ratio
= 2.6x10^13/3.92x10^10
= 6.63 x 10^2
