Question

Jane has a 5 × 7-inch photograph that she wants enlarged to a 10 × 14-inch photograph. What is the scale factor from the original photograph to the enlarged photograph?

Answer 1

I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.

Answer 2

2:1

Explanation:

it asks for the scale since 5 x 2 = 10 and 7 x 2 = 14

the scale is 2 : 1
