3/4 = 75%
A value like 75% shows up in everyday life when a store offers a discount, a phone battery is mostly charged, or a team wins three out of four games. It can also describe how much of a task is finished.
To picture it quickly, imagine a circle split into four equal slices, with three shaded in. You can also think of filling three of four cups or finishing three quarters of a playlist.
One common mix-up is thinking that 75% off means paying 75% of the original price. It actually means the discount takes away that share, leaving 25% of the original price to pay.
