3/80 = 3.75%
A value of 3/80, or 3.75%, might show up as a small fee, a discount, or the share of people in a group who choose a less common option. It’s the kind of amount that matters when you’re comparing prices or looking at survey results.
To picture it quickly, imagine about 4 out of every 100 items. That’s close to 3/80, so you can think of it as just under 4%—a small slice of the whole.
One common confusion is treating 3.75% as if it were 3.75 out of 10; it’s 3.75 out of 100. Also, a small percentage can still represent a lot when the total amount is large.
