Percent
Percent is used to express ratios in the form of a fraction with 100 as the denominator. In Latin, per cent means per hundred. Percents are usually written down using the internationally recognizable symbol % called the percent sign. Percent express the size of one quantity in relation to another quantity. The same relation can also be expressed with fractions or decimals. Like this:
56% = 0.56 = 56/100
Although percent can range in value from positive to negative infinity (you can actually say that a balloon increased its size by a million percent) and it does not have to be in the form of an integer (there is such a thing as 0.000002 percent), there are situations where the percentage can only be a value between 0 and 100.
When we talk about one part of a larger whole, the whole is considered to be the 100% and the part of that whole cannot be larger than that. For example, if you lose weight, you cannot lose more than 100% of your own weight (in theory – in practice the percent is way smaller than that).
The same thing is true when dealing with probability. The sum of probabilities of all possible outcomes in a single event cannot be greater than 100%. For instance, if you are tossing a coin that can only have two outcomes (heads or tails), there is a 50% chance that the outcome will be heads and a 50% chance the outcome will be tails (sildenafil citrate). If you are throwing a 10sided dice, each of the possible outcomes has a 10% chance of happening. The sum of all probabilities in an event is always 100%. Never more and never less. And a part of a whole is always smaller than the whole.
Percent can also be converted into fractions and/or decimals for easier calculation. If you wish to learn more about that subject, click convert percents, decimals and fractions.
