9/87 as a percentage is 10.34%. This fraction is a small part of a whole, and when you look at it in terms of percent, it shows just over ten percent.
The fraction 9/87 can also be simplified to 1/9, which still represents the same portion of a whole. Whether you write it as a fraction or a percent, it tells you the same thing: a little more than one‑tenth of the total.
Understanding both forms helps when comparing numbers. If you see 10.34% on a chart, you now know it comes from the simple fraction 9 out of 87. This makes it easy to switch between the two ways of looking at the data.
