2 7 As a Percent

A ratio is known as a fraction, in which one part of an answer is expressed as a fraction of the whole. For example, if a student earns an A, the fraction would equal 2/7, which is a little less than 1/3.

Answer

This percentage calculator is a tool that lets you do a simple calculation: what percent of X is Y? The tool is pretty straightforward. All you need to do is fill in two fields, and the third one will be calculated for you automatically. This method will allow you to answer the question of how to find a percentage of two numbers. Furthermore, our percentage calculator also allows you to perform calculations in the opposite way, i.e., how to find a percentage of a number. Try entering various values into the different fields and see how quick and easy-to-use this handy tool is. Is only knowing how to get a percentage of a number is not enough for you? If you are looking for more extensive calculations, hit the advanced mode button under the calculator. (

This is all nice, but we usually do not use percents just by themselves. Mostly, we want to answer how big is one number in relation to another number?. To try to visualize it, imagine that we have something everyone likes, for example, a large packet of cookies (or donuts or chocolates, whatever you prefer 😉 - we will stick to cookies). Let's try to find an answer to the question of what is 40% of 20? It is 40 hundredths of 20, so if we divided 20 cookies into 100 even parts (good luck with that!), 40 of those parts would be 40% of 20 cookies. Let's do the math: Remember that in decimal multiplication, you multiply as if there were no decimal points, and the answer will have as many “decimal digits” to the right of the decimal point as the total number of decimal digits of all of the factors. So when you multiply 0.7 × 80, think of multiplying 7 × 80 = 560. Since 0.7 has one decimal digit, and 80 has none, the answer has one decimal digit: 56.0 Thus, 0.7 × 80 = 56. When you are working in a role where you might deal frequently with taxes (for example in accountancy or the building trade), having a quick and easy way to calculate the tax in your head is very useful. In the UK, when VAT and CIS (Construction Industry Scheme) taxes are 20%, a handy mental maths hack is to work out 10% (move the decimal point one place to the left) and then double your answer to get 20%.

Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. For example, it is much convenient to say that percentage concentration of a specific substance is 15.7% than that there are 18.66 grams of substance in 118.66 grams of solution (like in an example in percentage concentration calculator). Another example is efficiency (or its special case - Carnot efficiency). Is it better to say that a car engine works with an efficiency of 20% or that it produces an energy output of 0.2 kWh from the input energy of 1 kWh? What do you think? We are sure that you're already well aware that knowing how to get a percentage of a number is a valuable ability. Do you have problems with simplifying fractions? The best way to solve this is by finding the GCF (Greatest Common Factor) of the numerator and denominator and divide both of them by GCF. You might find our GCF and LCM calculator to be convenient here. It searches all the factors of both numbers and then shows the greatest common one. As the name suggests, it also estimates the LCM which stands for the Least Common Multiple.Higher proportions use other notation (called parts-per notation), e.g., parts-per-million (PPM) which is frequently used to measure the concentration of a substance in solution or mixture. Of current concern is smog, the tiny particulate matter that enters the air and can seriously affect someone's health. Visit our smog calculator to see how many cigarettes do you "smoke" just by inhaling air and how can you counteract the spread of pollutions. After a delicious lunch, there's a time for a cup of coffee. It may sound quite weird for you, what do coffee and percentage have in common? Our coffee kick calculator tells you what your level of alertness is in percentages during the day! Check out how a dose of caffeine helps you remain focused! Also, if you're a real coffee-lover, try our other tools. With coffee to water ratio calculator, you can find a perfect ratio of ingredients to prepare your cup of coffee and caffeine calculator shows you how much caffeine you've had during a day. Be aware that you can overdose on caffeine too!

Recently, the percent symbol is widely used in programming languages as an operator. Usually, it stands for the modulo operation. On the other hand, in experimental physics, the symbol % has a special meaning. It is used to express the relative error between the true value and the observed value found in a measurement. To know more about relative error you can check our percent error calculator. Recently, the percent symbol is widely used in programming languages as an operator.

Percentages are very popular since they can describe situations that involve large numbers (e.g., estimating chances for winning the lottery), average (e.g., determining final grade of your course) as well as very small ones (like volumetric proportion of NOâ‚‚ in the air, also frequently expressed by PPM - parts per million).

Let's go with something a bit harder and four times more delicious: 400 cookies! We're dividing them evenly, and every compartment gets four cookies. Cookies look smaller, but in our imagination, they are the same, just the drawer is much bigger! One percent of 400 is 4. How about 15 percent? It's 15 compartments times four cookies - 60 cookies. Our tummies start to ache a little, but it has never stopped us from eating more cookies! So what is percentage good for? As we wrote earlier, a percentage is a way to express a ratio. Say you are taking a graded exam. If we told you that you got 123 points, it really would not tell you anything. 123 out of what? Now, if we told you that you got 82%, this figure is more understandable information. Even if we told you, you got 123 out of 150; it's harder to feel how well you did. A week earlier, there was another exam, and you scored 195 of 250, or 78%. While it's hard to compare 128 of 150 to 195 of 250, it's easy to tell that 82% score is better than 78%. Isn't the percent sign helpful? After all, it's the percentage that counts! (Source: www.omnicalculator.com)

Fraction

Other than being helpful with learning percentages and fractions, this tool is useful in many different situations. You can find percentages in almost every aspect of your life! Anyone who has ever been to the shopping mall has surely seen dozens of signs with a large percentage symbol saying "discount!". And this is only one of many other examples of percentages. They frequently appear, e.g., in finance where we used them to find an amount of income tax or sales tax, or in health to express what is your body fat. Keep reading if you would like to see how to find a percentage of something, what the percentage formula is, and the applications of percentages in other areas of life, like statistics or physics.

Percentage is one of many ways to express a dimensionless relation of two numbers (the other methods being ratios, described in our ratio calculator, and fractions).

Although Ancient Romans used Roman numerals I, V, X, L, and so on, calculations were often performed in fractions that were divided by 100. It was equivalent to the computing of percentages that we know today. Computations with a denominator of 100 became more standard after the introduction of the decimal system. Many medieval arithmetic texts applied this method to describe finances, e.g., interest rates. However, the percent sign % we know today only became popular a little while ago, in the 20th century, after years of constant evolution. (Source: www.omnicalculator.com)
