A fraction like 45/87 could describe how many people in a group chose a certain option, such as 45 out of 87 students preferring a school lunch. That’s 51.72%, so just over half the group.

To picture it quickly, imagine 100 dots: a little more than 51 would be shaded. It’s close to 52 out of 100, or just a bit above one-half.

One common mix-up is treating 45/87 as exactly half because the top number looks close to half of 87. It’s slightly more than half, and the percentage is an approximation rather than an exact whole-number value.
