Question

film with a width of 35 milimeters is projected onto a screen where the width is 5 meters. what is the scale factor of this enlargement? help please

Answer 1

You need to know how many times the width of the film would fit in the width of the screen, or: how many times 35 mm is equal to 5m. That number is the scale factor.

You'll understand you only can do this if the units are the same: comparing millimeters and meters is not so easy.

So it is probably best to convert 5 m to mm, and then look how many times 35 mm fits into that number.

So, look up the conversion between millimeters and meters. Convert the width of the screen into millimeters. Now divide the width of the screen by the width of the film. What do you get?
