Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.

On cross multiplication, we get


![[\because 1\ m=100\ cm]](https://tex.z-dn.net/?f=%5B%5Cbecause%201%5C%20m%3D100%5C%20cm%5D)
Therefore, the actual dimension is 3.84 m.
The dropdown numbers is an illustration of combination
The smallest dropdown number is 1025
<h3>How to determine the smallest dropdown number?</h3>
From the question, we have the following parameters:
- The dropdown number is 4-digit
- The digits are different.
We start counting from 1023, 1024, 1025, 1026...........
- The sum of digits in 1023 is 6, and the average is 1.5
- The sum of digits in 1024 is 7, and the average is 1.75
- The sum of digits in 1025 is 8, and the average is 2
The number 1025 satisfies the given conditions
Hence, the smallest dropdown number is 1025
