4/31 = ≈12.9%
Rounded to 2 decimal places.
A fraction like 4/31 can show up when 4 out of 31 people in a group choose the same option, such as a favorite lunch or school activity. That share is about 12.9%, so it represents a noticeable but fairly small part of the group.
To picture 4/31 quickly, imagine a group of about 30 people and count roughly 4 of them. It is a little less than one-eighth, since one-eighth is 12.5%, so estimating it as about 13% works well.
A common mistake is to think 4/31 is close to 4/30 and then treat it as exactly 1/7, even though those values are only approximate. It is also easy to confuse the numerator and denominator: the 4 tells how many are included, while the 31 tells the total group size.
