To find the percentage of heads, we can use the formula:
\[
\text{Percentage of heads} = \left( \frac{\text{Number of heads}}{\text{Total flips}} \right) \times 100
\]
In this case, Dave flipped the coin 12 times and got heads 5 times. Plugging in those values:
\[
\text{Percentage of heads} = \left( \frac{5}{12} \right) \times 100
\]
Calculating \( \frac{5}{12} \):
\[
\frac{5}{12} \approx 0.4167
\]
Now, multiply by 100:
\[
0.4167 \times 100 \approx 41.67
\]
Finally, rounding to the nearest whole number gives:
\[
\text{Percentage of heads} \approx 42\%
\]
Thus, the result is \( \boxed{42} \).
