Question

a microscope slide shows 45 red blood cells out of 75 blood cells. how many red blood cells would be expected in a sample of the same blood that has 450 cells

Answer 1

Come on atleast tell her how ha
Find the ratio: 45/75 = 0.6......Then multiply 450*0.6 = 270 red blood cells

Answer 2

I think you could use:
\[\LARGE \frac{45}{75}=\frac{x}{450}\]
Or yea, her way seems easier.
