7/28 = 25%
A value like 7/28, or 25%, might describe one out of every four days being rainy, or a quarter of a pizza being left over. You might also see it in a sale where an item’s price is reduced by a quarter.
To picture it quickly, imagine a whole divided into four equal parts and shade one part. That gives you a rough sense of how much 25% is without needing to count every piece.
One common mix-up is thinking 25% always means 25 things. It means a quarter of the total, so the actual number depends on how many things there are altogether.
