Answer: approximately 22 trillion blood cells
Step-by-step explanation:
total no. of bloods cells in Mrs.Murphy's body
=no. of blood cells in 1 cubic millimeter × no. of cubic millimeters
= 5,000,000×4,900.000
= 22,000,000,000,000 blood cells
The number of the red blood cells Mrs.Murphy has in her body total will be 24.5 × 10¹².
What are ratios and proportions?
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
One cubic millimeter of Mrs. Murphy's blood contains about 5,000,000 red blood cells.
There are about 4,900,000 cubic millimeters of blood in her body.
The number of the blood cell is directly proportional to the amount of blood.
Then the number of the red blood cells Mrs.Murphy has in her body total will be
Let x be the number of the blood cell.
Then we have
x / 5,000,000 = 4,900,000 / 1
x = 5,000,000 × 4,900,000
x = 24.5 × 10¹²
