Adoctor takes a sample of laura’s blood. there are 4.5*10^6 red blood cellsand 5000 white blood cells. how many times more red blood cells are there than white in the sample? (answer in scientific notations)

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
