Question

A microscope slide shows 37 red blood cells out of 60 blood cells . How many red blood cells would be expected in a sample of the same blood that has 900 blood cells

Answer 1

We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.

555 is our answer.
