Question from Debra:

An item on sale costs 55% of the original price. The original price was $\$51.$

Hi Debra,

If the item on sale cost 50% of the original price of $\$51$ then the sale price would be 50% of $\$51$ which is half of $\$51$ or $\$25.50.$ 50% is one half since $\large \frac{50}{100} = \frac{1}{2}.$

55% is $\large \frac{55}{100}$ so 55% of $\$51$ is $\large \frac{55}{100} \normalsize \times \$51.$
