25/100 = 25%
A value like 25% often shows up in everyday life as a store discount, a tip, or a battery level. For example, a 25% discount means an item costs less than its original price.
You can picture it as one quarter of a whole, like one slice out of a pizza cut into four equal pieces. That makes it easy to estimate: if something has 100 parts, 25% is about a quarter of them.
A common confusion is treating 25% as the same amount no matter what the whole is. A 25% discount saves more money on an expensive item than on a cheap one.
