FutureStarrWhat Percent Is 9 Out of 13 OR
One problem with number guessing games is that it takes on the feel of a cut-and-paste homework that would make even the most ardent math fans shiver in their boots. Yes, there are some clues hidden in the estimation rules—but finding the logic is another matter entirely.
Converting a percentage to a fraction or ratio is more complex. First, you must find the greatest common factor between the two numbers. Then you divide both the numerator and denominator by them. For instance, to simplify 5%, start by expressing it as 5/100. Then, divide the two numbers by their common factor, 5.Both percentages and fractions are ways to describe ratio. Ratio can be defined as the numerical relation between two figures which shows the number of times one value is contained within the other. To help you visualize it better, imagine a whole box broken into 100 equal parts, where each part is equivalent to a single percent. (Source: www.calculators.org)
In its most literal form, percentages mean “part per hundred.” This is the expression of a fraction or ratio where the denominator is 100. The percentage became one of the most popular expressions of fractions for a reason. They illustrate proportion and completeness in a way that’s easy to understand. They also simplify the process of calculating based on a proportion. Percentages convert to decimals, which are much easier to process.
It is forgivable to assume that the percentage sign "%" depicts a fraction. It does look like one at first glance, as does the division symbol, the obelus (÷). You may also question why the symbol has two zeroes in it. After all, isn’t dividing by zero undefined? Some sources claim that the two circles represent a shorthand for one hundred. That, while sort-of true, is not the whole story. The story behind it is much more complex. (Source: www.calculators.org)
