Answer:
1 : 6
Step-by-step explanation:
The given scale factor is ...
2 in : 1 ft
To express this as a ratio of pure numbers (without units), the units must be the same on either side of the colon (:). Here, we can make that happen by changing 1 ft to its equal in inches: 12 inches.
2 in : 1 ft = 2 in : 12 in = 2 : 12 = 1 : 6
We generally like to have the scale factor reduced to lowest terms, so we want to remove any common factors from the numbers.
The scale factor of 2 in to 1 foot is 1 : 6.
