Angular Magnification

Hi; Could someone please help me with this question: A small insect is placed 5.37 cm from a +5.84 cm focal length lens. a) Calculate the position of the image. b) Calculate the angular magnification.
For part a I used the lens equation 1/f = 1/d object + 1/d image, and I the position of the image to be -66.7cm...which is correct. However I can't get the right answer for the angular magnification. I used this equation: M =N/f + 1, but it doesn't give me the right answer. Can someone please help me with how to calculate angular magnification? Thanks.
angular magnification is defined by the equation m = 25 / f i beleive you are using the equation for max magnification
