Hello,

I'm having trouble understanding how and why the math is the way that it is to get the answer. The question states:

My question is: why do I have to do a division? I don't understand the why I have to do. I know how to do it, but why? How? How does micrometer/micrometer = minimum magnification? Can someone explain? The book says that the resolution of the human retina is about 150 micrometer. Please enlighten me.

Thanks!

I'm having trouble understanding how and why the math is the way that it is to get the answer. The question states:

**A specimen has a diameter of 1.5 micrometer. What is the minimum magnification that will allow a human to resolve this object?**

150 micrometer/1.5 micrometer = 100X <-- that is the answer150 micrometer/1.5 micrometer = 100X <-- that is the answer
