15/24 = 62.5%
A value like 15/24 can show up when tracking how much of a task is done, such as finishing 15 of 24 questions on an assignment. It means a little more than half is complete: 62.5%.
To picture it quickly, imagine splitting a whole into eight equal parts and shading five of them. That gives you a useful mental image of 15/24 without needing to work through the arithmetic.
One common mix-up is treating 15/24 as exactly 60%. It is slightly higher, so calling it “about 60%” is fine for a quick estimate, but it is not an exact match.
