Thank you:)

To solve the proportion 9/4 = ?/12, we need to find the missing value represented by the question mark.

To find the missing value, we can cross-multiply and then solve for the unknown.

Cross-multiplying means multiplying the numerator of the first fraction by the denominator of the second fraction, and then multiplying the denominator of the first fraction by the numerator of the second fraction.

In this case, we have (9)(12) = (4)(?), which simplifies to 108 = 4x.

To solve for ?, we divide both sides of the equation by 4:

108/4 = x

x = 27

So, the missing value in the proportion is 27.

Therefore, the correct answer is option D, 27.
