3/21 = ≈14.29%
Rounded to 2 decimal places.
A fraction like 3/21 can describe a small share of a group, such as 3 out of 21 students choosing the same lunch option. It represents about 14.29%, so it could also describe the portion of items in a survey, collection, or classroom that fit a certain category.
To picture 3/21 quickly, imagine 21 equal squares with only 3 shaded. That is a little less than one-sixth of the whole, so you can estimate it as roughly 14% without needing an exact value.
A common point of confusion is thinking that 3/21 is the same as 3.21 or reading it as a mixed number. The slash means “3 parts out of 21 equal parts,” not a decimal with the digits 3 and 21 placed side by side.
