3/75 = 4%
A value like 4% can show up in everyday life as a small sales tax, a service fee, or the share of people in a group who choose a certain option. It is a useful way to describe a small part of a larger amount.
To picture it quickly, imagine 100 items lined up: about 4 of them would make up this amount. It is a little less than 1 out of every 20 items.
One common point of confusion is mixing up 4% with 0.4%; the decimal point makes the second value ten times smaller. It also helps to remember that a percentage describes a share, not a fixed number of items.
