1  discounted price / normal price is the discount, multiply by 100% to get a percent.

$9 is obviously 9/10 of $10. 19/10 = 1/10 or 10% Now try the harder one.

Yep thats great 9.65 divided by 10 = 0.965 10 .965 = 9.035 so 9.03 % ? But if I get my calculator and go 10  9.03 % = I get $ 9.09 not $ 9.65
