1/2 = 50%
A value like 1/2, or 50%, shows up when you split something evenly, like sharing a pizza between two people or getting half the questions right on a quiz. It can also describe a sale that takes half off the original price.
To picture 1/2 quickly, imagine a shape or group divided into two equal parts, with one part shaded or chosen. If you’re estimating, ask whether the amount looks about the same as the amount left over.
One common confusion is treating “half” as half of the original amount when the reference has changed. For example, half of a smaller serving is less than half of a larger serving.
