6/40 = 15%
A value like 6/40, or 15%, can show up in everyday life when a store advertises a discount or a survey reports how many people chose an option. It could also describe six out of forty students bringing lunch from home.
To picture it quickly, imagine splitting a group of forty people into ten equal groups of four. Six people is a little more than one of those groups, so 15% is a bit more than one-tenth of the whole.
A common point of confusion is mixing up 15% with 15 people. The percentage describes a share of a group, so the number of people it represents depends on how large the group is.
