31/100 = 31%
A value of 31% might show up in a survey, such as the share of students who walk to school, or in a store discount. It describes a portion of a larger group or amount.
To picture 31/100, imagine 100 small squares with 31 shaded in. It’s a little less than one-third, so you can estimate it as just under 33 out of every 100.
A common mix-up is treating 31% as 31 whole items, no matter how large the group is. It means 31 out of each 100, so the actual number depends on the total amount.
