A student observes and draws an Amoeba, using the high power lens of a microscope. The diameter of the drawing is 100mm. The actual diameter of the Amoeba is 100um. What is the magnification of the drawing?
a) 0.001
b) 100
c) 400
d) 1000
Thanks for the answers :p

Magnification = size in drawing/actual size
Therefore magnification = 100mm/100um
Obviously we need the values in the same units so as 100um = 0.1mm we can deduce
magnification = 100mm/0.1mm = 1000
So the answer is D.
