Camera Lens Magnification

1. The problem statement, all variables and given/known data

A camera lens has focal length 55mm and an object is 500mm away. Calculate the position of the image and the magnification (or reduction)

2. Relevant equations

1/u + 1/v = 1/f

u = Object Distance

v = Image Distance

f = focal length

m = magnification

3. The attempt at a solution

f = 55

u = 500

1/500 + 1/v = 1/55

1/55 – 1/500 = 1/v

55-1 – 500 -1 = 0.01618

ANS-1 = 61.79 so approximately 62mm

v/u = m

62/500 = 0.124M

Did I go with the right approach? Any help would be great.
