I have a big math test tomorrow and a question on the review packet my teacher made for my class just doesn't make sense to me. Here it is... For a 'Black Friday' sale, everything in a store is 10% off the original price. If Ana purchased an item that was marked with a sale price of $40, what was the original price?

My teacher said the answer was $44.44 but I don't understand how she got that, can someone help please?

What is Percentage?

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

No; percent is not greater than decimal. Percent is LESS than the number is decimal.

In fact, take any number---decimal or other wise, and divide that number by "100" to convert is to its form in "percent".
_______________________________________...

"Percent" mean "per hundred"--or "parts per hundred".
_______________________________________...
0.14 is less than "140%".

140% = 140 parts per hundred = 140/100 = 1.40 ---> 1.40 > 0.14
_______________________________________...
Note: 0.14 = 14/100 = (0.14*100) %= 14 parts per hundred = 14%

140% > 14%
