To express 15% as a fraction, start by understanding that the term "percent" means "per hundred." Therefore, 15% can be written as 15 per 100, or mathematically:

\[

15\% = \frac{15}{100}

\]

Next, simplify this fraction. Both 15 and 100 can be divided by their greatest common divisor, which is 5:

\[

\frac{15 \div 5}{100 \div 5} = \frac{3}{20}

\]

Thus, 15% as a fraction simplifies to 3/20. This fraction is correctly expressing the percentage in the required form. The other options do not simplify to represent 15% accurately when compared to 3/20, which confirms that it is the correct choice.
