What Is 2 12 As a Percent

A simple garden textbook can teach you how to answer this question, but it can be a little more difficult in real life. In this article, we’ll talk about how the numerical expression "2 12" can be a percentage. After that, you'll find a quiz to test your knowledge of percentages and some helpful multiplications tips.

Percent

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:

The term percent is often attributed to Latin per centum, which means by a hundred. Actually, it is wrong. We got the term from Italian per cento - for a hundred. The percent sign % evolved by the gradual contraction of those words over centuries. Eventually, cento has taken the shape of two circles separated by a horizontal line, from which the modern % symbol is derived. The history of mathematical symbols is sometimes astonishing. We encourage you to take a look at the origin of the square root symbol! (Source: www.omnicalculator.com)

 

Divide

In this case it can be helpful if, instead of thinking of the division symbol ‘÷’ as meaning ‘divided by’, we can substitute the words ‘out of’. We use this often in the context of test results, for example 8/10 or ‘8 out of 10’ correct answers. So we calculate the ‘number of managers out of the whole staff’. When we use words to describe the calculation, it can help it to make more sense. 0.225 is the fraction of staff that are managers, expressed as a decimal. To convert this number to a percentage, we need to multiply it by 100. Multiplying by 100 is the same as dividing by a hundred except you move the numbers the other way on the place values scale. So 0.225 becomes 22.

As your maths skills develop, you can begin to see other ways of arriving at the same answer. The laptop example above is quite straightforward and with practise, you can use your mental maths skills to think about this problem in a different way to make it easier. In this case, you are trying to find 20%, so instead of finding 1% and then multiplying it by 20, you can find 10% and then simply double it. We know that 10% is the same as 1/10th and we can divide a number by 10 by moving the decimal place one place to left (removing a zero from 500). Therefore 10% of £500 is £50 and 20% is £100. When we divide something by 100, we simply move the place values two columns to the right (or move the decimal point two places to the left)\

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%.

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). 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).
