The Basics of Percentages
Percentages are a way of expressing a number as a fraction of 100. They are often used to express how much something has changed. For example, if the price of a stock goes up by 10%, this means the price has gone up by 10% of its original value. In this case, we would say that the stock increased by 10 percentage points.
What is a percentage?
In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, “%”, or the abbreviations “pct.”, “pct”; sometimes the abbreviation “pc” is also used. A percentage is a dimensionless number (pure number). Because percentages are dimensionless, they can be expressing using any unit of measurement. For example, 58% can be expressed as 58 per thousand, 58 000 ppm (parts per million), or 0.058.
What is a proportion?
In mathematics, a proportion is an equation stating that two ratios are equal. A proportion is a special type of relationship between two ratios. When we set up a proportion, we use the following notation:
a : b = c : d
This says that the ratio of a to b is equal to the ratio of c to d. In other words, the two ratios are equivalent.
What is the percentage formula?
To calculate a percentage, we need to multiply the fraction by 100. For example, 58 out of 70 can be expressed as a fraction: 58/70. To calculate the percentage, we need to multiply this fraction by 100 like so: (58/70)*100=82.86%.
How to Calculate Percentages
Percentages are a way of expressing a number as a fraction of 100. They are often used to communicate how large or small a number is in comparison to another number. For example, 58 out of 70 can be written as 58%.
Step One: Convert the problem to an equation using the percentage formula: P% * X = Y
To calculate a percentage, we need to convert the problem to an equation using the percentage formula: P% * X = Y.
Remember, the symbol “%” means “per 100”, so 58% means 58 per 100 or, put another way, 58 out of 100. We can use this information to set up our equation like this:
P% * X = Y
58% * X = 70
Now that we have our equation set up, we can solve for “X” by using algebra. First, we’ll divide both sides by 58%:
(58% * X)/58% = 70/58%
X = 70/58%
X = 120/58
X = approximately 2.06
Step Two: Isolate the variable Y. Y = P% * X
In the example above, Y would be 58 and X would be 70. This means that you need to solve for what percentage 58 is of 70. In order to do this, set up a fraction with Y over X. In this case it would be 58/70. Then, you need to change this fraction into decimal form. The way to do this is by finding a equivalent fraction with a denominator of 100. This is easily done by multiplying both the numerator and denominator by 2. This gives you 116/140. To change a fraction into decimal form, divide the numerator by the denominator so in this case it would be 116/140 = .82857142857143. Since we’re solving for what percentage 58 is of 70, we can say that 58/70 = .82857142857143 or in other words, 82.857142857143%
Step Three: Plug in the values and solve for X. X = Y/P%
Now let’s do a couple of examples to see how this works in the real world. Remember, our equation is X = Y/P%. We just need to plug in the values for Y and P%, and then solve for X.
Example 1: What is 58 out of 70 as a percentage? In this case, Y is 58 and P% is 70. So our equation becomes X = 58/70%. We can solve this equation by cross multiplication. This means that we will multiply both sides of the equation by P%. So on the left side of the equation, we will have (X)(P%), and on the right side we will have (Y). Here’s what that looks like with our values plugged in:
(X)(70%) = 58
Now we can solve for X by dividing both sides by 70%. This gives us the answer X = 82.86%. So 58 out of 70 as a percentage is 82.86%.
Example 2: What is 95 out of 400 as a percentage? In this case, Y is 95 and P% is 400. So our equation becomes X = 95/400%. We can solve this equation by cross multiplication just like before. This means that we will multiply both sides of the equation by P%. So on the left side of the equation we will have (X)(P%), and on the right side we will have (Y). Here’s what that looks like with our values plugged in:
(X)(400%) = 95
Now we can solve for X by dividing both sides by 400%. This gives us the answer X = 23.75%. So 95 out of 400 as a percentage is 23.75%.
Examples
To find out what 58 out of 70 as a percentage , you need to find out what 70% is of 58. 70% of 58 is 40.6. Therefore, 58 out of 70 as a percentage is 40.6%.
Example One: What is 20% of 80?
To calculate 20% of 80, simply multiply 20% by 80.
20% of 80 = 16
Example Two: What is 58% of 70?
To find 58% of 70, we first multiply 70 by 0.58 to get 40.6. We can also say that 58% of 70 is the same as 58 per 100 of 70 which is the same as 58 parts per 100 of 70.
Example Three: What is 75% of 300?
To calculate 75% of 300, we first multiply 75 by 300.
75% of 300 = (75 x 300) ÷ 100
75% of 300 = 22500 ÷ 100
75% of 300 = 225
