4/64 = 6.25%
A value like 6.25% can show up as a small discount, a service fee, or a chance of something happening. For example, a store might offer a 6.25% discount on an item, though the exact savings would depend on its price.
To picture 6.25%, think of a little more than 6 out of every 100 things. It’s also about one out of every 16, so you can imagine one marked spot in a group of 16 equal spots.
A common mistake is to read 6.25% as 6.25 whole units instead of 6.25 out of 100. It’s a small share, not more than six out of every ten.
