    First find the amount of the discount. This is the part. Then divide the part by the total original price and multiply by 100 to find the percent.

    Yes, the part is 9. Now you are trying to find what percent of 45 is 9. Since 9 is the part, divide the part (9) by the whole (45) and multiply by 100.

    50% means half. Half of 45 is 22.5 9 has to be much less than 50%.

    How many of these problems have you solved? 9 is what % of 45?

    Correct. 20% is correct. Check: What is 20% of 45? 20% of 45 = 20% * 45 = 0.2 * 45 = 9, and 9 was the discount. Also notice that 9 is one-fifth of 45, and 0.2 and 20% are other ways of representing 1/5.
