How do you write \[9/100\] as a percent?

Hint: In the given question, we have been asked to convert the given number into percent. To do that, we just need to apply the simple formula of percent. Percent is – given by whole, multiplied by 100. After calculating the result, we just add the percent sign after the answer. We just simply have to calculate \[\dfrac{9}{{100}}\] in percent form.

Complete step by step answer:
We are going to use the formula of percent, which is:
\[Percent = \dfrac{{Given{\rm{ Quantity}}}}{{Whole}} \times 100\]
The given number is \[\dfrac{9}{{100}}\].
To convert it to percent, we simply multiply it by \[100\], and we have,
\[\dfrac{9}{{100}} \times 100 = 9\% \]

Hence, \[\dfrac{9}{{100}} = 9\% \]

Note: In the given question, we had to convert a given fraction to percent. We did that by multiplying the fraction with hundred. The point where some students make mistakes is when they do not convert the percent to its lowest term. This would cost some marks. Also, some students make mistakes by not adding the percent sign at the end of the percent expression. So, it is important to keep these points in mind.
