Complete: \[ \frac{3}{4}=\frac{?}{16} \]

Step 1 ：Given the equation \(\frac{3}{4} = \frac{?}{16}\)

Step 2 ：We need to find a number that when divided by 16 gives the same result as 3 divided by 4. This is a simple cross multiplication problem.

Step 3 ：Cross multiply to get \(3 * 16 = 4 * ?\)

Step 4 ：Solve for ? to get \(? = \frac{3 * 16}{4}\)

Step 5 ：Calculate the value to get ? = 12.0

Step 6 ：Final Answer: The missing number is \(\boxed{12}\)
