A fraction like 272/686, or about 39.65%, could describe the share of students who walk or bike to school, customers who choose a certain product, or survey participants who give a particular answer. It shows up whenever a group is being compared with the total group.
You can picture it as a little less than 4 out of every 10 items. On a 100-square grid, shade about 40 squares, leaving slightly more than 60 unshaded.
