What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
The price of an item yesterday was 115. Today the price fell to 69.
The difference in price = 115 - 69 = 46
