In mathematics, a percentage (from Latin: percento, “hundred”) is a number or ratio expressed as a fraction of 100. It is often denoted using percent sign, “%,” although the abbreviations “pct.”, “pct” and sometimes “pc.” A percentage is a dimensionless number (pure number); it has no unit of measure.
Let us consider, for example, that you want to buy a smartwatch to gift your friend. The price of the watch in the market is 80 USD, but somehow you come to know that price of a smartwatch will get reduced within a few days. The estimated decrease in the price would be 40 percent of the actual price of the watch. You want to make an estimate of the amount of reduction by calculating 40% of the 80. For this, you multiply 0.4 by 80 and get 32 which is a substantial amount of reduction. These types of examples are common in our daily life.
