Your little brother has a toy car he rides. It is modeled on a real car scale of 1.4. You decide to make your model to a scale of 1;16. You measure your brother's toy car and use it to find the dimensions of the car it was modeled after.

If you have to model to a scale of 1:16, then, you have to divide the dimensions of the real car by 16.
If the length is 6.4 m, after dividing by 16 we have: 0.4 m
If the height is 1.6 m, after dividing by 16 we have: 0.1 m
The answer is:
The length of your model car must be: 0.4 m
The height of your model car must be: 0.1 m
