 Compare percentages to fractions When comparing percents to decimals write the fractions as percentages and compare. Which is greater, $\frac{3}{20}$ or 16%? Write $\frac{3}{20}$ as a percent: $\frac{3}{20}=\frac{15}{100}=15%$ 15% is less than 16%. So, 16% is the greater number. Which is greater? $\frac{19}{3}$ is greater 2% is greater neither; they are equal
