2/10 = 20%
A value like 20% shows up in everyday life when a store advertises a discount, a recipe calls for part of a batch, or a survey reports how many people chose an option. It’s a useful way to describe a portion without needing to count every item.
To picture 20% quickly, imagine a row of 10 equal boxes with 2 shaded. You can also think of it as about one-fifth of a whole, which makes it easier to estimate amounts in your head.
A common mix-up is treating 20% as the same amount no matter what the total is. A 20% discount saves more money on an expensive item than on a cheap one, because the percentage is taken from different starting amounts.
