1. Problem Description

The problem asks to find the missing number in the equation $? \div 100 = 0.12$. The answer should be written as a whole number or decimal.

2. Solution Steps

Let the missing number be $x$. The equation can be written as:

$x \div 100 = 0.12$

To solve for $x$, multiply both sides of the equation by 100:

$x \div 100 \times 100 = 0.12 \times 100$

$x = 0.12 \times 100$

To multiply $0.12$ by $100$, we move the decimal point two places to the right.

$x = 12.00$

$x = 12$

3. Final Answer

The missing number is 12.
