11/55 = 20%
A share like 20% can show up in everyday life as a store discount, a tip, or the portion of a class that chose a certain answer. It helps describe a part of a larger group in a way that’s easy to compare.
To picture it quickly, imagine 10 equal boxes with 2 shaded, or 5 equal groups with 1 shaded. That gives you a rough sense of how much of the whole it is.
A common mix-up is treating 20% as 20 out of 20, when it means 20 out of every 100. Also, a 20% discount does not mean the item costs 20% of its original price; it means that amount is taken off.
