Magnification should b decided in two ways such as by sign and by magnitude. First see the sign is + means image is virtual and erect. If the sign is - ve image is real and inverted. Now given sign is -ve means it is real and inverted. Similarly if the magnitude is less than 1 it is diminished. Equal to 1 means same size. And if it is greater than 1 image is enlarged.
