102/480 = 21.25%
A value like 102/480, or 21.25%, could describe how many students in a school walk or bike to class. It might also represent the share of a household budget spent on groceries, transportation, or another regular expense.
You can picture 21.25% as a little more than one-fifth of the whole. If a group has 100 items, imagine about 21 of them, with a small extra amount beyond that.
A common mistake is treating 21.25% as if it were 21.25 whole items, even when the total is not 100. The percentage describes a portion of the total, so the actual number represented by 102/480 depends on the size of the group.
