When you turn 4/100 into a percent, you get 4.00%. This tells you that out of every 100 parts, 4 parts are being considered.
The fraction 4/100 is a simple way to show a small portion of a whole. It can be reduced to 1/25, but keeping it as 4/100 makes the link to the percent clear and easy to read.
In everyday life, 4.00% might show up on a price tag, a test score, or a small tax rate. It’s a quick way to see how tiny a part of something is compared to the entire amount.
