15/50 = 30%
A value of 15/50, or 30%, can show up in everyday life when 30 out of every 100 items meet a condition. For example, a store might mark down 30% of its clothing, or 15 of 50 students might choose the same lunch option.
You can picture 30% as about one-third of a group, though it is a little less than one-third. In a group of 50, imagine splitting the items into five equal groups of 10 and shading three of those groups.
A common mistake is thinking that 30% means 30 items no matter how large the group is. The percentage stays the same, but the actual number changes depending on the total amount.
