Question

Answer 1

2.6x10*13=26,000,000,000,000
3.92x10^10=39,200,000,000
26 trill. Divide 39 b. =663.3
So 663 more times

Answer 2

Answer:

6.63 x 10^2 times

Step-by-step 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
