Just a question for anyone who is doing bio? If you are asked to find the actual size of a cell and they give u a scale bar. Do you do Actual length of scale bar/ measured length of the scale bar. Then you use that scale factor and times it by the measured length of drawing to get the actual cell size. Right? I just need clarification because I feel like I'm doing it wrong
based on what i've learnt (which is not the most lets be honest), yes it pretty much is just actual length of scale bar divided by the measured length of scale bar and then multiplied by the measured size of the cell

I think u do rationalise the denominators for both fractions then minus. But it might be wrong

rationalise the denonimators, then there shouldn't be any fractions, and the root 5s will cancel each other out (you'll see why)
