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: 50 / 100 × 40 / 100 = 0.50 × 0.40 = 0.20 = 20 / 100 = 20%. It is not correct to divide by 100 and use the percent sign at the same time; it would literally imply division by 10,000.
The percent sign % (sometimes per cent sign in British English) 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.
The top 20% of Americans owned 86% of the country's wealth and the bottom 80% of the population owned 14%. In 2011, financial inequality was greater than inequality in total wealth, with the top 1% of the population owning 43%, the next 19% of Americans owning 50%, and the bottom 80% owning 7%. [15]
A logarithmic scale (or log scale) is a method used to display numerical data that spans a broad range of values, especially when there are significant differences between the magnitudes of the numbers involved. Unlike a linear scale where each unit of distance corresponds to the same increment, on a logarithmic scale each unit of length is a ...
This time can be calculated by dividing the natural logarithm of 2 by the exponent of growth, or approximated by dividing 70 by the percentage growth rate (more roughly but roundly, dividing 72; see the rule of 72 for details and derivations of this formula).
The formula implies that dividing the nominal GDP by the real GDP and multiplying it by 100 will give the GDP Deflator, hence "deflating" the nominal GDP into a real measure. [1] It is often useful to consider implicit price deflators for certain subcategories of GDP, such as computer hardware.
1.23444... = 1.23 + 0.00444... = 123 / 100 + 4 / 900 = 1107 / 900 + 4 / 900 = 1111 / 900. or alternatively 1.23444... = 0.79 + 0.44444... = 79 / 100 + 4 / 9 = 711 / 900 + 400 / 900 = 1111 / 900; 0.3789789... = 0.3 + 0.0789789... = 3 / 10 + 789 / 9990 = 2997 / 9990 + 789 / 9990 = 3786 / 9990 = 631 / 1665
The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm ...

In solutions, mass concentration is commonly encountered as the ratio of mass/ [volume solution], or m/v. In water solutions containing relatively small quantities of dissolved solute (as in biology), such figures may be "percentivized" by multiplying by 100 a ratio of grams solute per mL solution. The result is given as "mass/volume percentage".
