23/115 = 20%
A value like 23/115, or 20%, can show up when about one out of every five people in a group chooses the same option. For example, it could describe the share of students who ride the bus, customers who use a coupon, or voters who support a proposal.
To picture 20% quickly, imagine dividing a group into five equal parts and focusing on one part. It is also close to one-fifth, so in a group of 100 items, you would expect about 20 of them.
A common mistake is thinking 20% means 20 items no matter how large the group is. The actual number changes with the total, even though the proportion stays the same.
