If you have the fraction $\displaystyle \frac{7}{18}$ how do you figure out what percentage that is? I know the answer is about 39% but how do you do the work to figure it out? Thanks
You want to write this as a percentage, which is an equivalent way to write a proportion, meaning "per hundred". You need to remember that 100% is the same as 1. You also need to remember that multiplying by 1 keeps your fraction the same. So that means:
$\displaystyle \displaystyle \begin{align*} \frac{7}{18} &= \frac{7}{18} \cdot 1 \\ &= \frac{7}{18} \cdot 100\% \\ &= \frac{700}{18}\% \end{align*}$
