45/72 = 62.5%
A value like 62.5% can show up when a store marks an item down, a student gets a score, or a phone battery is partly charged. It describes a little more than half of the whole.
To picture 45/72 quickly, think of a bar that is a bit over halfway filled. It is also close to five-eighths, which can make it easier to imagine.
A common mix-up is treating 62.5% as the same as 62%, even though the extra half-percent can matter in precise scores or measurements. Also, a percentage describes a share of a whole, so the whole amount matters when comparing two values.
