7/20 = 35%
A value of 7/20, or 35%, might describe a discount on a jacket, the share of students who chose a certain lunch, or how much of a project is finished. It’s a little more than one-third, so it can represent a noticeable portion without being close to half.
To picture it quickly, imagine 20 equal slices of something and shade 7 of them. You can also think of it as a bit more than three out of every ten.
One common mix-up is treating 35% as if it means 35 out of 20, rather than 35 out of 100. Also, “35% off” means the price is reduced by that share, not that you pay only that share.
