Answer:
Red blood cells are 900 times of white blood cells in the blood sample of Laura.
Step-by-step explanation:
Sample of Laura's blood sample contains number of red plus cells = 4.5 and number of white blood cells = 5×
Now we calculate the ratio of red blood cells and white blood cells
= 4.5×÷5
= 4.5×÷5
= 4500÷5
=900
Now scientific representation of data will be
Test Result Range
White Blood Cells 5×per 5-10
Red Blood Cells 4.5× per 4.2-6.11
Number of red blood cells =
Number of white blood cells = 5000 or we can write this as
We have to find how many times more red blood cells are there than white in the sample. so we will divide the two to get the answer.
=
= = 9*10*10 = 900
Hence, the red blood cells are 900 times more than white blood cells.
