### How to get a percentage – An easy guide for anyone who needs help with basic math

Want to know how to get a percentage? If you’re in need of help with basic math, this guide will show you the steps you need to take in order to find the percent of any given number or set of numbers. It’s easy, and it’s something that anyone can do no matter how little or how much math experience they have under their belt!

Understanding what numbers and percentages are
In order to understand how to calculate percentages, you first need to understand what numbers and percentages are. A number is simply a value that can be represented by digits, while a percentage is a way of representing a number as a fraction of 100. For example, the number 12 can be represented as 12%, or 0.12, or 1/8.

The number 25 can be represented as 25%, or 0.25, or 1/4. To see this in action, take a look at the following equation: \$1 + \$2 = \$3 . The result (\$3) represents 100% since it’s equal to all three values (1+2). However, if we want to find out what percentage each term equals then we would plug in the appropriate values into our equation. So for instance if we plug in 2 for \$1 and 3 for \$2 then we have 25% * 50% = 12.5%.

Converting from one unit of measurement to another
Did you know that there are multiple ways to get a percentage? In this post, we’ll explore how to get a percentage using the most common method: converting from one unit of measurement to another. By the end of this post, you’ll be able to confidently calculate percentages without any trouble! Let’s get started!
First, convert your original unit of measurement into the new desired unit of measurement.

Then multiply by 100 and subtract the number from 100 (e.g., 10% = 10/100=0.10). Finally, convert back to your original unit of measurement by multiplying by your original number (e.g., 0.10*10=1). For example, if I wanted to convert 5 feet into inches: 5 ft*12 in/ft = 60 in/ft-5 ft=55 in/ft. Converting back again will give me my answer: 55in*12in/ft = 660 in2 ft-5 ft=655 in2 ft

Multiplying by 100
In order to get a percentage, you need to multiply the decimal by 100. This is because there are 100 percent in a whole. So, if you have 0.5, this is equivalent to 50 percent. You can use this method when you’re trying to find what percent one number is of another number. For example, let’s say you want to know what percent 4 is of 16.

You would take 4 and divide it by 16 to get 0.25. Then, you would multiply that by 100 to get 25 percent. To make it easier to do calculations, many people prefer to use percentages as decimals (0.25). The word percent comes from per centum which means per hundred. If you had 1% or 10%, for example, these numbers are equal to 1/100 and 10/100 respectively. To calculate the other way around, just flip over your calculator so that your answer will be on top and then divide the two numbers. For instance, if I wanted to know what 2% was in decimals I would type: 200/(2*100) = 0.01

Dividing by 100
When you want to find a percentage of a number, the first step is always to divide by 100. Dividing by 100 is the same as moving the decimal point two places to the left. So, if we wanted to find 19% of 80, we would divide 80 by 100 like this 80 ÷ 100 = 0.8
19 ÷ 100 = 0.19
0.8 x 0.19 = 0.148 which means that 19% of 80 is about 148 .

If we wanted to know how much the cost of living in the U.S. has increased over ten years, and someone told us it had increased by 10%, then 10% of what? You can’t just say 10% because that’s not clear: did they mean 10% of something else? Or did they mean 10% more than what we had before? We have to give an amount as well: so it would be 10% of \$100.00, which equals \$10.00.

Converting into different bases (decimal, hexadecimal, octal, binary etc.)
In mathematics, a base is the number of different digits or combination of digits that a system of counting uses to represent numbers. When we count in decimal (base 10), we use the digits 0 through 9. We can also use other bases, like binary (base 2), hexadecimal (base 16), and octal (base 8). Each base has its own advantages and disadvantages.

In this post, we’ll focus on how to convert between different bases. Converting from decimal to another base involves doing some simple division. To convert from any other base to decimal, you need to know what the value of each digit in the new base is worth (ie. converting from hexadecimal into decimal requires knowing what each digit in hexadecimal means)

Introduction to percents
A percent is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %, or sometimes as pct. For example, 50% (read as fifty percent) is equal to 50/100, or one-half. To calculate a percent of a quantity, multiply the quantity by the decimal form of the percent. For example, to find 19% of 120:
120 x 0.19 = 22.8
You can also use this formula to express any part-to-whole relationship as a percent.

For example, if there are 12 oranges in a bag and you take out 2 of them, what percentage of the remaining 10 do you have? 10/12 = 83%. In another example, if there are two thirds cups in a pot and you add one more third cup to it then you will have 1 full cup. That’s an increase of 50%.

Percentages word problems
You’re at the store and see an item you want that’s on sale for 20% off. How much will you save? To calculate the answer, you need to know how to calculate a percentage.
Here’s how: Take the original price of the item and multiply it by the decimal form of the percent. So, in this case, you would take 20% (0.2) and multiply it by the original price.

Then, subtract that number from the original price to find out how much you’ll save. In this example, if the item was originally \$100, you would take 0.2 x 100 = \$20 off, so your final cost would be \$80.
