The fraction 50/80 is equal to 62.50% when converted to a percentage. This means that 50 out of 80 parts represent about five-eighths or just over three-fifths of the whole. It's a bit more than half, but not quite two-thirds.
In everyday situations, you might see this percentage used to describe things like test scores, sales discounts, or progress towards a goal. For example, if you answered 50 out of 80 questions correctly on a quiz, you'd have scored 62.50%. Or if a store was offering a 62.50% discount, they'd be reducing prices by just over five-eighths of the original cost.
