What is \( 200 \% \) of \( 18 ? \) 9 \( \begin{array}{l}11.1 \\ 27 \\ 36\end{array} \)

To find \( 200 \% \) of \( 18 \), you simply multiply \( 18 \) by \( 2 \) (because \( 200 \% = 2 \)). So, \( 18 \times 2 = 36 \). Thus, the answer is \( 36 \)! Now, here’s a fun fact: Percentages originated from the concept of "per hundred" in ancient mathematics. The use of percentages can be traced back to the way merchants calculated taxes and interest rates during the Middle Ages! Another interesting tidbit is that percentages are a fantastic way to compare data. For example, if two items are priced differently, using percentages helps you see which item's discount is more significant, making shopping a bit more straightforward and budget-friendly!
