Introduction
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); there are various strategies for dealing with percentages when they arise in calculations.
The Basics of Percentages
To calculate a percentage, you take a portion of a whole and multiply it by 100. So, 18 out of 19 as a percentage would be (18/19)*100, or 94.7%. Fourteen out of 19 would be (14/19)*100, or 73.6%.
What is a percentage?
A percentage is a way to express a number 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); it has no unit of measure.
There are different ways to express numbers as percentages. The most common way is to express a given number as a certain percentage of another number. For instance, 45% can be expressed as 45/100, .45, or 45:100. Another common way to express percentages is with decimal notation; for example, 1% can be expressed as .01 or 100%.
When working with percentages, it is important to keep in mind that the whole must always equal 100%. This means that if you have two numbers that are being added together to equal 100%, they cannot both be expressed as percentages. For instance, if you have two numbers that you want to add together and get 100%, you cannot both express them as percentages. You would need to convert one of them to a decimal before adding them; for example, 60% and 40% can be expressed as .6 and .4, which when added together equals 1 (100%).
Percentages can be used in many different situations. They are often used in financial contexts, such as when expressing interest rates or changes in stock prices. They are also commonly used in academic contexts, such as when discussing grades or test scores. Additionally, percentages are frequently used in surveys and polls in order to report results.
What is a decimal?
A decimal is a number that represents a fraction where the denominator is some power of 10. For example, the decimal 0.45 represents the fraction 45/100. To convert a decimal to a percent, multiply by 100. So 0.45 = 45/100 = 0.45 × 100 = 45%.
What is a fraction?
A fraction (from Latin fractus, “broken”) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (e.g. 1/2, 2/5, 3/4) consists of an integer numerator displayed above (or before) a line (or slash), and a non-zero integer denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions and complex fractions..
Converting 18 out of 19 to a Percentage
To convert a fraction to a percentage, you need to multiply the fraction by 100. In this case, you would multiply 18 by 100 to get 1,800%. This answer can be rounded to 1,818% for simplicity.
Step One: Convert the fraction to a decimal
To turn a fraction like 18/19 into a percentage, start by converting the fraction into a decimal. To do this, divide the top number of the fraction (the numerator) by the bottom number (the denominator). In other words, divide 18 by 19.
18 ÷ 19 = .947
Step Two: Multiply the decimal by 100
The next step is to multiply this answer by 100. This will move the decimal point two places to the right and give you a percentage.
.947 × 100 = 94.7%
Step Two: Convert the decimal to a percentage
To convert a decimal to a percentage , multiply it by 100. So, 0.18 × 100 = 18%. This means that 18 out of 19 can be written as 18%.
Conclusion
18 out of 19 as a percentage is approximately 94.7%.
