15/218 = ≈6.88%
Rounded to 2 decimal places.
A fraction like 15/218 can show up when 15 people out of a group of 218 share the same result, such as students choosing a certain club or customers selecting a particular product. That makes it a small but noticeable portion, equal to about 6.88%.
To picture it quickly, imagine 218 tiny squares with only 15 shaded in. You can also estimate it as about 7 out of every 100, which is close enough for a quick comparison.
A common mistake is to treat 15/218 as if it were 15/200, which makes the portion seem slightly larger than it really is. It is also easy to confuse the numerator and denominator, even though the denominator represents the total group.
