    Magnification = observed size/actual size. Do you have either the observed or actual size of the nucleus?

    Hey man yeah sorry we were given the actual size I didn't see it, it's OK though as I've solved it. Could you perhaps please help me with this next question? A chloroplast is 94 mm long; the scale is 20 mm is equivalent to 3 micrometres, what is the actuAl size of the chloroplast? Thanks

    I’m not really sure, I haven’t done questions like this in lesson. Would you divide 94 by 20 and then convert it to micrometers? I don’t know, sorry I couldn’t help more.
