To find the missing number, you can set up the equation based on the information given. We know that 75% of some number equals 12.
Let \( x \) be the missing number. The equation can be written as:
\[ 0.75x = 12 \]
To solve for \( x \), divide both sides of the equation by 0.75:
\[ x = \frac{12}{0.75} \]
Calculating the right side:
\[ x = 12 \div 0.75 = 12 \times \frac{100}{75} = 12 \times \frac{4}{3} = 16 \]
So, the missing number is \( 16 \).
