Question

A small legend on the corner states that 4 inches of the length corresponds to an length of 52 get what is the scale factor

Answer 1

52 is 13 times bigger than 4, so the  scale fatore is 13 or 1:13 as a ratio (although im not sure when the length of 53 is being measured in)

52:4 is the scale, but they probably want it in the simplest form
so 13:3
