What is one half of $\dfrac{1}{100}$ of $9000$?
I need to find one half of $\dfrac{1}{100}$ of $9000$. To do that, I can multiply $9000$ by $\dfrac{1}{100}$ and then divide the result by $2$. Multiplying $9000$ by $\dfrac{1}{100}$ is the same as dividing $9000$ by $100$, which gives me $90$. Then dividing $90$ by $2$ gives me $45$. Therefore, one half of $\dfrac{1}{100}$ of $9000$ is $45$.
