4/10 = 40%
The fraction 4/10, or 40%, can show up in everyday life when 4 out of 10 seats on a bus are occupied or when 40% of students in a class choose pizza for lunch. It describes a part of a group, amount, or chance.
You can picture 4/10 quickly as a little less than half. Imagine a row divided into 10 equal parts with 4 shaded, or think of 40 cents out of a dollar.
A common mistake is assuming 40% is close to 50%, when it is actually 10 percentage points lower. It can also be confusing because 4/10 may look different from 2/5, even though they represent the same amount.
