What percent is this of the width color slide

Reference no: EM13687575

Here is the problem which I am struggling on, please help me!

Problem: During a lunar eclipse, a picture of the moon (which has a diameter of 3.48 × 10⁶m and is 3.86 × 10⁸m from the earth) is taken with a camera whose lens has a focal length of 320mm.

Question- What percent is this of the width of a 24mm × 36mm color slide?

I need experts help in the above question.
