The average adult human has approximately 2.5 ×10^13 red blood cells and 7×10^9 white blood cells. About how many times as great is the number of red blood cells than the number of white blood cells? Write and solve an equation.

Respuesta :

The number of red blood cells is 3571 times more than white blood cells.

Step-by-step explanation:

Given,

Amount of red blood cells = [tex]2.5*10^{13}[/tex]

Amount of white blood cells = [tex]7*10^9[/tex]

Let,

x represent the number of times red blood cells are greater from white blood cells.

Therefore;

Red blood cells = White blood cells * x

[tex]2.5*10^{13}=(7*10^9)x[/tex]

Dividing both sides by 7*10^9

[tex]\frac{2.5*10^{13}}{7*10^9}=\frac{(7*10^9)x}{7*10^9}\\\\0.3571*10^{13-9}=x\\x=0.3571*10^4\\x=0.3571*10000\\x=3571[/tex]

The number of red blood cells is 3571 times more than white blood cells.
