2/80 = 2.5%
A value like 2/80, or 2.5%, can show up when only a small number of people in a group choose a certain option. For example, it could describe 2 students out of 80 bringing lunch from home or 2 items out of 80 being damaged.
To picture 2.5% quickly, imagine a group of 80 people with just 2 of them highlighted. It is a very small share—about 1 out of every 40—so it is closer to “a few” than to 5% or 10%.
A common mistake is thinking that 2/80 is the same as 2/8 because both numbers contain a 2 and an 8. The extra zero makes the fraction much smaller, so 2/80 represents a tiny portion of the whole.
