To solve the inequality \( 45d \leq 24 \), follow these steps:
-
Divide both sides by 45 (since 45 is positive, the direction of the inequality remains the same):
\[ d \leq \frac{24}{45} \]
-
Simplify \(\frac{24}{45}\):
To simplify, find the greatest common divisor (GCD) of 24 and 45, which is 3.
\[ \frac{24 \div 3}{45 \div 3} = \frac{8}{15} \]
So, the solution to the inequality is:
\[ d \leq \frac{8}{15} \]
