Percentage in the context of Percent sign

The terms Islamic world and Muslim world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.

The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology during the Islamic Golden Age. Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. The Islamic conquests, which culminated in the Caliphate being established across three continents (Asia, Africa, and Europe), enriched the Muslim world, achieving the economic preconditions for the emergence of this institution owing to the emphasis attached to Islamic teachings. In the modern era, most of the Muslim world came under European colonial domination. The nation states that emerged in the post-colonial era have adopted a variety of political and economic models, and they have been affected by secular as well as religious trends.

A property tax (whose rate is expressed as a percentage or per mille, also called millage) is an ad valorem tax on the value of a property.

The tax is levied by the governing authority of the jurisdiction in which the property is located. This can be a national government, a federated state, a county or other geographical region, or a municipality. Multiple jurisdictions may tax the same property.

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).

There are many ways to test porosity in a substance or part, such as industrial CT scanning.

Economic activity rate, EAR (or labor force participation rate, LFPR) is the percentage of the population, both employed and unemployed, that constitutes the workforce, regardless of whether they are currently employed or job searching.

This figure is a measure of the degree of success of the economy in engaging the population in some form of production of services or goods.

The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.

In the table below, the first two columns identify ethnolinguistic groups. Subsequent columns represent the sample size (n) of the study or studies cited, and the percentage of each haplogroup found in that particular sample.

In any quantitative science, the terms relative change and relative difference are used to compare two quantities while taking into account the "sizes" of the things being compared, i.e. dividing by a standard or reference or starting value. The comparison is expressed as a ratio and is a unitless number. By multiplying these ratios by 100 they can be expressed as percentages so the terms percentage change, percent(age) difference, or relative percentage difference are also commonly used. The terms "change" and "difference" are used interchangeably.

Relative change is often used as a quantitative indicator of quality assurance and quality control for repeated measurements where the outcomes are expected to be the same. A special case of percent change (relative change expressed as a percentage) called percent error occurs in measuring situations where the reference value is the accepted or actual value (perhaps theoretically determined) and the value being compared to it is experimentally determined (by measurement).

In accounting, liquidity (or accounting liquidity) is a measure of the ability of a debtor to pay their debts as and when they fall due. It is usually expressed as a ratio or a percentage of current liabilities. Liquidity is the ability to pay short-term obligations.

In a tax system, the tax rate is the ratio (usually expressed as a percentage) at which a business or person is taxed. The tax rate that is applied to an individual's or corporation's income is determined by tax laws of the country and can be influenced by many factors such as income level, type of income, and so on. There are several methods used to present a tax rate: statutory, average, marginal, flat, and effective. These rates can also be presented using different definitions applied to a tax base: inclusive and exclusive.

Strain has dimension of a length ratio, with SI base units of meter per meter (m/m).Hence strains are dimensionless and are usually expressed as a decimal fraction or a percentage.Parts-per notation is also used, e.g., parts per million or parts per billion (sometimes called "microstrains" and "nanostrains", respectively), corresponding to μm/m and nm/m.

Commissions are a form of variable-pay remuneration for services rendered or products sold. Commissions are a common way to motivate and reward salespeople. Commissions can also be designed to encourage specific sales behaviors. For example, commissions may be reduced when granting large discounts. Or commissions may be increased when selling certain products the organization wants to promote. Commissions are usually implemented within the framework on a sales incentive program, which can include one or multiple commission plans (each typically based on a combination of territory, position, or products).

Payments are often calculated using a percentage of revenue, a way for firms to solve the principal–agent problem by attempting to realign employees' interests with those of the firm. However, models other than percentages are possible, such as profit-based approaches, or bonus-based approaches. Commissions allow sales personnel to be paid (in part or entirely) based on products or services sold, rather than just hourly or based on attempted sales. Although many types of commission systems exist, a common methodology to manage total spend is known as on-target earnings. On-target earnings represent a salesperson's base pay, plus expected commissions (assuming the salesperson meets a quota). On-target earnings help salespersons estimate their expected total compensation, should they meet company-specified goals.
