A drawing of a cell on a poster is 10cm and the scale shows it to have an actual size of 0.1mm in real life. Calculate the magnification.

Correct answer: C. magnification = image/actual; Where image = 10cm, and actual =0.1mm. covert 0.1mm to cm, this will be 0.01cm. Therefore, magnification = image/actual, magnification = 10cm/0.01cm, Magnification = x1000) - ×10 000 B is incorrect since you have to convert the 0.1mm to cm.
