130/260 = 50%
A value like 130/260, or 50%, shows up whenever something is split evenly into two parts. For example, it could describe half of a group choosing one option, half of a tank being full, or a store discount that cuts a price in half.
You can picture it quickly as one of two equal sections being shaded. Since 130 is exactly half of 260, the value is right in the middle: neither more nor less than half.
A common mistake is thinking 50% means 50 out of every 100 items only. It can describe any amount that is half of the total, even when the numbers are larger, like 130 out of 260.
