75/375 = 20%
A value like 75/375, or 20%, can show up in everyday life when a store offers a discount or when one out of every five items has a certain feature. For example, if 20% of students in a class ride the bus, that could be about 6 students in a class of 30.
You can picture 20% as one-fifth of a whole, since five equal parts would make 100%. To estimate it quickly, imagine splitting a group into five equal sections and taking one section.
A common mistake is thinking 20% means 20 out of every 100 items only, instead of recognizing that it represents the same proportion in any-sized group. It is also easy to confuse 20% with 0.20 or 20 percentage points, even though those terms can be used differently depending on the situation.
