"be found by multiplying first, so in this example the 50 would be multiplied by 100 to give 5,000, and this result would be divided by 1250 to give 4%. To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is: It is not correct to divide by 100 and use the percent sign at the same time. (E.g. , not , which actually is .

Another kind of fraction is the percentage (Latin ""per centum"" meaning ""per hundred"", represented by the symbol %), in which the implied denominator is always 100. Thus, 51% means 51/100. Percentages greater than 100 or less than zero are treated in the same way, e.g. 311% equals 311/100, and −27% equals −27/100. The related concept of ""permille"" or ""parts per thousand"" (ppt) has an implied denominator of 1000, while the more general parts-per notation, as"
"Rule of twelfths The rule of twelfths is an approximation to a sine curve. It can be used as a rule of thumb for estimating a changing quantity where both the quantity and the steps are easily divisible by 12. Typical uses are predicting the height of the tide or the change in day length over the seasons. The rule states that over the first period the quantity increases by 1/12. Then in the second period by 2/12, in the third by 3/12, in the fourth by 3/12, fifth by 2/12 and at the end of the sixth period reaches"

Three of these diminished fourths form major triads with perfect fifths, but one of them forms a major triad with the diminished sixth. If the diminished sixth is a wolf interval, this triad is called the wolf major triad. Similarly, we obtain nine minor thirds of 300 ± 3""ε"" cents and three minor thirds (or augmented seconds) of 300 ∓ 9""ε"" cents. In quarter-comma meantone, the fifth is of size , about 3.42157 cents (or exactly one twelfth"
"Percentage In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, ""%"", or the abbreviations ""pct."", ""pct""; sometimes the abbreviation ""pc"" is also used. A percentage is a dimensionless number (pure number). For example, 45% (read as ""forty-five percent"") is equal to , 45:100, or 0.45. Percentages are often used to express a proportionate part of a total. If 50% of the total number of students in the class are male, that means that 50 out of every 100 students are male. If there are 500 students,"

"Percent sign The percent (per cent) sign (%) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign ‰ and the permyriad (per ten thousand) sign ‱ (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand respectively. Higher proportions use parts-per notation. English style guides prescribe writing the number and percent sign without any space between. However, the International System of Units and ISO 31-0 standard prescribe a space between the number and percent sign,"
"on goods sold at auction known as ""centesima rerum venalium"". Computation with these fractions was equivalent to computing percentages. As denominations of money grew in the Middle Ages, computations with a denominator of 100 became more standard and from the late 15th century to the early 16th century it became common for arithmetic texts to include such computations. Many of these texts applied these methods to profit and loss, interest rates, and the Rule of Three. By the 17th century it was standard to quote interest rates in hundredths. The term ""per cent"" is derived from the Latin ""per centum"","
"a .500 winning percentage has won 50% of their matches. The practice is probably related to the similar way that batting averages are quoted. As ""percent"" it is used to describe the steepness of the slope of a road or railway, formula for which is 100 × which could also be expressed as the tangent of the angle of inclination times 100. This is the ratio of distances a vehicle would advance vertically and horizontally, respectively, when going up- or downhill, expressed in percent. Percentage is also used to express composition of a mixture by mass percent and mole percent."
"in 75 ""parts per million"" (ppm), means that the proportion is 75/1,000,000. Whether common fractions or decimal fractions are used is often a matter of taste and context. Common fractions are used most often when the denominator is relatively small. By mental calculation, it is easier to multiply 16 by 3/16 than to do the same calculation using the fraction's decimal equivalent (0.1875). And it is more accurate to multiply 15 by 1/3, for example, than it is to multiply 15 by any decimal approximation of one third. Monetary values are commonly expressed as decimal fractions with denominator 100, i.e.,"
"Twelfth root of two The twelfth root of two or is an algebraic irrational number. It is most important in Western music theory, where it represents the frequency ratio of a semitone () in twelve-tone equal temperament. Historically this number was proposed for the first time in relationship to musical tuning in 1580 (drafted, rewritten 1610) by Simon Stevin. It allows measurement and discussion of equal intervals (frequency ratios) as equally spaced. A semitone is 100 cents (1 cent = ). The twelfth root of two to 20 significant figures is .

"Save percentage Save percentage (often known by such symbols as SV%, SVS%, SVP, PCT) is a statistic in many sports that track ""saves"" as a statistic. In ice hockey and lacrosse statistic that represents the percentage of shots on goal a goaltender stops. It is calculated by dividing the number of saves by the total number of shots on goal. Although the statistic is called ""save ""percentage"""", it is given as a decimal (in the same way as an on-base percentage in baseball). Thus, "".933"" means a goaltender saved 93.3 percent of all shots they faced. National Hockey League goaltenders"
"meaning ""by the hundred"". The sign for ""per cent"" evolved by gradual contraction of the Italian term ""per cento"", meaning ""for a hundred"". The ""per"" was often abbreviated as ""p."" and eventually disappeared entirely. The ""cento"" was contracted to two circles separated by a horizontal line, from which the modern ""%"" symbol is derived. The percent value is computed by multiplying the numeric value of the ratio by 100. For example, to find 50 apples as a percentage of 1250 apples, first compute the ratio = 0.04, and then multiply by 100 to obtain 4%. The percent value can also"

A simple non-dyadic fraction such as 1/3 can be approximated as 341/1024 (0.3330078125), but the conversion between dyadic and decimal (0.333) or vulgar (1/3) forms is complicated. Instead, either decimal or vulgar fractions can be represented natively in finger binary. Decimal fractions can be represented by using regular integer binary methods and dividing the result by 10, 100, 1000, or some other power of ten. Numbers between 0 and 102.3, 10.23, 1.023, etc. can be represented this way, in increments of 0.1, 0.01, 0.001, etc. Vulgar fractions can be represented by"
"proportion is usually estimated through an unbiased sample statistic obtained from an observational study or experiment. For example, the National Technological Literacy Conference conducted a national survey of 2,000 adults to determine the percentage of adults who are economically illiterate. The study showed that 72% of the 2,000 adults sampled did not understand what a gross domestic product is. The value of 72% is a sample proportion. The sample proportion is generally denoted by formula_3 and in some textbooks by formula_4. A proportion is mathematically defined as being the ratio of the values in a subset formula_5 to the values"

For example, moving up from 40% to 44% is a 4 ""percentage point"" increase, but is an actual 10 percent increase in what is being measured. In the literature, the percentage point unit is usually either written out, or abbreviated as ""pp"" or ""p.p."" to avoid ambiguity. After the first occurrence, some writers abbreviate by using just ""point"" or ""points"".

"72 equal temperament In music, 72 equal temperament, called twelfth-tone, 72-tet, 72-edo, or 72-et, is the tempered scale derived by dividing the octave into twelfth-tones, or in other words 72 equal steps (equal frequency ratios). Each step represents a frequency ratio of , or cents, which divides the 100 cent ""halftone"" into 6 equal parts (100 ÷ = 6) and is thus a ""twelfth-tone"" (). 72 being divisible by 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72, 72-tet includes those equal temperaments. This division of the octave has attracted much attention from tuning theorists, since"
"Winning percentage In sports, a winning percentage is the fraction of games or matches a team or individual has won. It is defined as wins divided by the total number of matches played (i.e. wins plus draws plus losses). A draw counts as a ½ win. For example, if a team's season record is 30 wins and 20 losses, the winning percentage would be .600. If a team's season record is 30–15–5 (i.e. it has won thirty games, lost fifteen and tied five times), the five tie games are counted as 2½ wins, and so the team has an adjusted"
