To obtain a magnification of, -0.5 with a convex lens, the object should be placed:

A convex lens produces a magnification of +5. The object is placed;

If a Magnification of, -1 (minus 1) is obtained by using a converging lens, and then the object has to be placed:

An object is 0.09 m from a magnification lens and the image is formed 36 cm from the lens the magnification produced is:

To obtain a magnification of, -2 with a convex lens of focal length 10 cm, the object should be placed:
