10/50 = 20%
A value like 10/50, or 20%, can show up in everyday life as a discount, a survey result, or the chance of rain. For example, a store might mark an item down by 20%, or a poll might find that 20% of people prefer a certain option.
A quick way to picture 20% is as one-fifth of a whole. Imagine splitting a pizza into five equal slices: 20% is one slice.
One common mix-up is confusing 20% with 20 percentage points. A change from 20% to 40% is an increase of 20 percentage points, but it is a 100% increase compared with the original amount.
