13/64 = ≈20.31%
Rounded to 2 decimal places.
A value like 13/64, or 20.31%, might describe a little more than one-fifth of something, such as a discount on a store item or the share of a group that chose a particular option. It is a useful way to talk about amounts that are close to one-fifth but not exactly.
To picture it quickly, imagine 64 equal pieces and shade 13 of them. For a rough estimate, think of it as about one-fifth, while remembering it is just a bit more.
One common point of confusion is treating 13/64 as exactly one-fifth. One-fifth is a handy estimate, but it is slightly smaller than 13/64.
