To solve the expression \(12 + 12:16\), it's important to clarify how to interpret the colon. If we treat it as a division, the expression can be rewritten as:
\[ 12 + \frac{12}{16} \]
Now, simplify \( \frac{12}{16} \):
\[ \frac{12}{16} = \frac{3}{4} \]
Now, we can convert the whole number 12 to a fraction to add it to \( \frac{3}{4} \):
\[ 12 = \frac{48}{4} \]
Now, add:
\[ \frac{48}{4} + \frac{3}{4} = \frac{48 + 3}{4} = \frac{51}{4} \]
Thus, the final result is:
\[ \frac{51}{4} \quad \text{or} \quad 12.75 \]
If a different interpretation of the colon was intended, please let me know!
