Ratio can be defined as the numerical relation between two figures which shows the number of times one value is contained within the other. In the most familiar model of arithmetic, you can go ahead and say it’s 100%.īoth percentages and fractions are ways to describe ratio. Of course, you don’t need to fret at all if you deal with 99.9999(…)%. In most practical cases, it’s not an issue. You can, of course, get an approximate answer by rounding it off. To display these as exact values, you must express them as fractions. With this in mind, how simple can this fraction go? The common factor of the two numbers is 5. Here’s how we can turn 37.5% into a decimal, fraction, and ratio: For instance, 37% will be 37/100 because the common factor between the two numbers is 1. Often, you can simplify many percentages by leaving them as is. Remember that your denominator is always 100, and not all numbers will share its factors. To convert to a ratio, change the slash into a colon. Then, divide the two numbers by their common factor, 5. For instance, to simplify 5%, start by expressing it as 5/100. Then you divide both the numerator and denominator by them. First, you must find the greatest common factor between the two numbers. Thus, 2% is 0.02 and 50% is 0.5.Ĭonverting a percentage to a fraction or ratio is more complex. When you already have the decimal value, move the decimal point two places to the left. Divide the fraction to get its decimal value, then multiply it by 100.įor our first example, let’s find the percentage value of 6/8: The easiest percentage conversion is through decimals. You have several ways of converting a fraction into a percentage. Likewise, you can express any fraction, decimal, or ratio as a percentage. Thus, you can convert them into ratios, decimals, or other fractions.
A single percentage point, 1%, is equal to the fraction 1/100. All percentages are numbers divided by 100. Much like fractions, percentages represent parts of a whole. Besides convenience, this is especially true when it comes to expensive purchases and investments. Grasping basic percentages is a vital skill that can help you save time and money. They all mean something different in context, yet use the same expression. You can find them in banks and stores to video game inventories. Its usefulness in everyday arithmetic is evident wherever you look. Percentages convert to decimals, which are much easier to process. They also simplify the process of calculating based on a proportion. They illustrate proportion and completeness in a way that’s easy to understand. The percentage became one of the most popular expressions of fractions for a reason. In its most literal form, percentages mean “part per hundred.” This is the expression of a fraction or ratio where the denominator is 100. When you catch the news, the weather anchor says there’s 30% chance of rain in your area. A retail store is offering up to 50% off on jeans till the end of the month. For instance, when you check your mobile phone, its battery life is expressed in percent. Even if your work does not involve a lot of computing or mathematical concepts, you’re bound to encounter it now and then. We might not notice it, but percentages are quite common in daily life. in words: subtract the original number from the final number, multiply this result by 100 (move the decimal 2 places to the right) and then divide this value by the original number to get percent changeĪ Practical Guide to Pervasive Percentages.in words: divide the desired resultant percent by 100 to convert it to a decimal, then multiply it by the original number to solve for the number which is associated with that percent of the original number.in words: divide x by y to get its decimal number & then multiply by 100 to convert the decimal into a percent.Here are instructions for the formulas to calculate common percent related math problems:
