To solve the inequality \( 45d \leq 24 \), we need to isolate \( d \). We do this by dividing both sides of the inequality by 45:
\[ d \leq \frac{24}{45} \]
Now, simplify \( \frac{24}{45} \):
\[ \frac{24}{45} = \frac{8}{15} \]
Thus, the solution to the inequality is:
\[ d \leq \frac{8}{15} \]
So, the final answer is:
d ≤ \(\frac{8}{15}\).
