3/15 = 20%
A value like 3/15, or 20%, might show up in a survey where 3 out of 15 people choose the same option. You might also see it in a sale, a recipe, or a progress tracker.
To picture it quickly, imagine a group of 15 things and set aside 3 of them. That’s about one out of every five, so it’s a manageable portion rather than a tiny amount.
One common mix-up is thinking 3/15 means 3% because the fraction starts with 3. The bottom number matters too: it tells you the 3 is part of a group of 15.
