If a student scores 80% on a test, what fraction represents this score in simplest form?

An 80% score can be represented as a fraction by understanding the relationship between percentages and fractions. Percent means "per hundred," so 80% can be expressed as 80 out of 100, or 80/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 20.

When we divide 80 by 20, we get 4, and when we divide 100 by 20, we get 5. Therefore, 80/100 simplifies to 4/5. This fraction accurately reflects the original percentage score in its simplest form, demonstrating how a percentage can be converted to a fractional representation.
