25/50 = 50%
A value like 25/50, or 50%, shows up in everyday life when a store advertises half off or when a team wins half of its games. It can also describe a test where someone gets half the questions right.
To picture it quickly, imagine a pizza cut into two equal halves: 25/50 represents one of those halves. It’s also about the same as filling a glass halfway.
A common mix-up is thinking 50% always means “50 out of 100” in the original group. The percentage stays the same even when the group has a different number of items, as it does with 25 out of 50.
