Question

there are many different types or parasites. This fact is easy to see when they're magnifier, for example at a patio pf 12:1, in cm. If the image of a parasite is 9cm, how large is it in real life?

Answer 1

ha ha, will give u a simple logic.. if it would have been pf 9 cm.. than you could see that with naked eyes.. No Telescope required :-p

But this is not the part of the solution..

The microscope magnifies 1 unit object to 12 units

so 1 -----> 12
x -----> 9

x = 9/12 = 3/4 = 0.75 cm...
