53/79 expressed as a percentage is 67.09%. This value tells you how much of a whole the fraction represents when you think in terms of 100 parts instead of 79 parts.
The fraction 53/79 is already in its simplest form, meaning the numerator and denominator share no common factors other than 1. It sits a little more than two‑thirds of a whole, which is why the percentage is just above 66%.
Seeing the number as a percentage makes it easier to compare with other values that are also expressed out of 100. For example, a test score of 67.09% would be just a touch higher than a 66% grade.
In everyday situations, you might round the percentage to 67% for quick estimates, but the more precise 67.09% is useful when exactness matters, such as in scientific calculations or financial reports.
