Question

A doctor takes a sample of Laura's blood. There are 4.5 x 10 To the sixth power red blood cells and 5000 white blood cells. How many times more red blood cells are there than white in the sample? (Answer in standard notation)

Answer 1

900 times

Explanation:

A doctor takes a sample of Laura's blood. There are
`4.5 * 10^(6)` red blood cells and 5000 white blood cells.

Now, we are asked to get how many times more red blood cells are there than white blood cells in the sample.

There were
`4.5 * 10^(6)` = 4500000 red blood cells in the sample.

Hence,
`(4500000)/(5000) = 900`

And there are 900 times more red blood cells than white blood cells in the sample. (Answer)
