Final answer:
To find the bedroom's length in the scale model, multiply the actual length of 16 feet by the scale factor of 1/10, which results in 1.6 feet for the model's bedroom length.
Step-by-step explanation:
To find the length of a bedroom in the scale model of a house that is 1/10 the size of the actual house, you can create a multiplicative comparison. If the actual bedroom is 16 feet long, the length of the same bedroom in the scale model would be 16 feet multiplied by the scale factor of 1/10.
Therefore, the expression to use is 16 feet × 1/10, which equates to 1.6 feet in length for the bedroom in the model.
