Answer

45%

Work Step by Step

We want to write a fraction as a percent, so we first turn the fraction into a decimal. $9/20=.45$. To write a decimal as a percent, we multiply by 100. Thus, we move the decimal point two places to the right, and then we add a percent symbol. Therefore, .45 becomes 45%.
