If you cannot read it, let me know.
Percents to a decimal is easier to understand just take the percent so say it is 35% the decimal form would be .35 or 5% .05, and for the percent to a fraction just take the percent such as 30/100 and make sure it is in the simplest form to solve so that would be 3/10.
