A poster is 60 cm wide. It was created as an enlargement of a photo 24 cm wide. What scale factor was used to create the poster? (
To find the scale factor, we compare the width of the poster to the width of the original photo.
Scale factor = width of the poster / width of the original photo
Scale factor = 60 cm / 24 cm
Simplifying the fraction:
Scale factor = 5/2
So, the scale factor used to create the poster was 2.5.
