The given answer, "20%, 20%", is the correct representation of 0.2 as a percent. To convert a decimal to a percent, we move the decimal point two places to the right and add the percent symbol. In this case, moving the decimal point two places to the right gives us 20, and adding the percent symbol gives us 20%. The additional "20 %" is redundant and not necessary, but it still represents the correct conversion.
