Surely, you mean 6.5 and 8.2? (Smoking)
 
oh yeah my bad. the decimal values are .65 and .82 but as percentages it would be 6.5 and 8.2

To convert decimals to percentages, you have to move the decimal point two places, since $100=10^2$.

$$0.65=65\%$$

$$0.82=82\%$$
 
well originally it was 0.065 and 0.082 but i forgot the zeros and i didnt feel like going back to fix em :o
