To solve the equation \( 24 + 12 = \text{blank} \times (8 + 4) \), we first simplify the right side of the equation.
1. Calculate \( 8 + 4 \):
\[
8 + 4 = 12
\]
2. Now the equation can be rewritten as:
\[
24 + 12 = \text{blank} \times 12
\]
3. Next, simplify the left side:
\[
24 + 12 = 36
\]
4. Now we have:
\[
36 = \text{blank} \times 12
\]
5. To find the value of "blank," divide both sides by 12:
\[
\text{blank} = \frac{36}{12} = 3
\]
Thus, the missing value in Ming’s equation is **3**.
