84/560 = 15%
A value like 84/560, or 15%, can show up in everyday life as a discount, a survey result, or the portion of students in a group who choose a certain option. For example, 15% of a store’s customers might use a special coupon during a sale.
You can picture 15% as about 15 out of every 100 items, or roughly 1 out of every 7 people. It is a little less than one-fifth, since one-fifth is 20%, so it helps to imagine a group divided into five equal parts with slightly less than one full part shaded.
A common mistake is thinking that 15% means 15 out of 560, instead of recognizing that the fraction compares 84 with the total of 560. It is also easy to confuse 15% with 0.15%—the latter is much smaller.
