To find the value of \( D \) in the equation \( 11.66 + 3.D8 = 15.24 \), we first need to isolate \( 3.D8 \) by subtracting \( 11.66 \) from both sides of the equation:
\[
3.D8 = 15.24 - 11.66
\]
Now we perform the subtraction:
\[
15.24 - 11.66 = 3.58
\]
Thus, we have:
\[
3.D8 = 3.58
\]
Now, let's analyze the number \( 3.D8 \). The digit \( D \) is the tenths place between the 3 and the 8. To make \( 3.D8 \) equal to \( 3.58 \):
- The digit in the tenths place of \( 3.58 \) is \( 5 \).
Thus, we find that:
\[
D = 5
\]
The value of \( D \) is \( \boxed{5} \).
\[
3.D8 = 15.24 - 11.66
\]
Now we perform the subtraction:
\[
15.24 - 11.66 = 3.58
\]
Thus, we have:
\[
3.D8 = 3.58
\]
