You place an object 16.6 cm in front of a diverging lens which has a focal length with a magnitude of 12.2 cm. Determine how far in front of the lens the object should be placed in order to produce an image that is reduced by a factor of 4.40.
It says the answer is 115 cm, but I do not know how to get that answer.
