How to calculate percentage of a number

Calculator Use This online calculator converts a percent to a fraction. If the percent value is greater than 100% it is converted into a mixed number fraction. Enter percents to convert them into fractions. The number you enter can also have decimal places as in 3.5% or 0.625%. To convert a percent to a fraction you first convert the percent to a decimal then use the same procedure as converting a How to Convert a Percent to Fraction • Divide the percentage by 100 to get a decimal number. • Use that number as the numerator (top) of a fraction. Put a 1 in the denominator (bottom) of the fraction. • Convert the decimal to a whole number: Count how many places are to the right of the decimal. If you have x decimal places then multiply numerator and denominator by 10 x. • Reduce the fraction: Find the Greatest Common Factor (GCF) of the numerator and denominator and reduce the fraction by dividing both numerator and denominator by the GCF. • Simplify the remaining fraction to a mixed number fraction if possible. Example: Convert 35.5% to a fraction 1. Divide by 100

A percent frequency distribution can be used to understand what percentage of a distribution is composed of certain values. The following step-by-step example shows how to create a percent frequency distribution in Excel. Step 1: Create the Data First, let’s create a dataset that contains information about 20 different basketball players: Step 2: Calculate Frequencies Next, we’ll use the UNIQUE() function to produce an array of unique team values in column A: Next, we’ll use the COUNTIF() function to count the number of times each team appears: Step 3: Convert Frequencies to Percentages Next, we’ll convert each frequency to a percentage by dividing each individual frequency by the sum of the frequencies: Next, we’ll highlight each of the values in column F and click the percentage (%) icon in the Number group along the top ribbon: Each value will automatically be displayed as a percentage: From the output we can see that: • 35% of all players belong to team A • 25% of all players belong to team B • 15% of all players belong to team C • 25% of all players belong to team D Note that the percentages add up to 100%. Additional Resources The following tutorials offer additional information on how to calculate frequencies in Excel:

How much is 15 percent of 210? How about 75 percent of 440 or 350 percent of 20? The standard way of calculating percentages can make these problems difficult to do without a calculator. Luckily, there are several tips and tricks you can use to solve percentage problems without a calculator. Once you understand these simple methods, these questions become easy to solve. It is valuable to know the origin of the term ​ percent​ if you want to truly understand how to calculate a percentage. The word ​ percent​ comes from the phrase per cent. ​ Cent​ is a root that means one hundred, so per cent literally means per one hundred. For example, if you know that 30 percent of the students in a school are boys, that means that there are 30 boys per one hundred students. Another way to say this is that 30 out of 100 students are boys. Generally, the way to figure out any percentage is to multiply the number of items in question, or ​ X​, by the ​ decimal​ form of the percent. To figure out the decimal form of a percent, simply move the decimal two places to the left. For example, the decimal form of 10 percent is 0.1. Then, to calculate what 10 percent of is, say, 250 students, simply multiply the number of students by 0.1. In this way you can combine 5 percent, 10 percent, 25 percent, and 50 percent to calculate a wide variety of percentages in your head. If you need to calculate a percentage that is not a multiple of 5, you can use this technique to estimate the answer very closely...

In word problems involving percentages, remember that the sum of all parts of the whole is 100 % 100\% 1 0 0 % 100, percent . For example, if a teacher has graded 60 % 60\% 6 0 % 60, percent of an assignment, then they have not graded 100 − 60 % = 40 % 100-60\%=40\% 1 0 0 − 6 0 % = 4 0 % 100, minus, 60, percent, equals, 40, percent of the assignment. 60 % 60\% 6 0 % 60, percent and 40 % 40\% 4 0 % 40, percent are complementary percentages: they add up to 100 % 100\% 1 0 0 % 100, percent . % change = final − initial initial × 100 \%\,\text\times100 % change = initial final − initial ​ × 1 0 0 percent, start text, c, h, a, n, g, e, end text, equals, start fraction, start text, f, i, n, a, l, end text, minus, start text, i, n, i, t, i, a, l, end text, divided by, start text, i, n, i, t, i, a, l, end text, end fraction, times, 100 • Your answer should be • an integer, like 6 6 6 6 • a simplified proper fraction, like 3 / 5 3/5 3 / 5 3, slash, 5 • a simplified improper fraction, like 7 / 4 7/4 7 / 4 7, slash, 4 • a mixed number, like 1 3 / 4 1\ 3/4 1 3 / 4 1, space, 3, slash, 4 • an exact decimal, like 0.75 0.75 0 . 7 5 0, point, 75 • a multiple of pi, like 12 pi 12\ \text 2 / 3 pi 2, slash, 3, space, start text, p, i, end text Check Explain • Your answer should be • an integer, like 6 6 6 6 • a simplified proper fraction, like 3 / 5 3/5 3 / 5 3, slash, 5 • a simplified improper fraction, like 7 / 4 7/4 7 / 4 7, slash, 4 • a mixed number, like 1 3 / 4 1\ 3/4 1 3 / 4 1, space, 3...

• Find % of a number: Place the number in column A and the % in column B. In column C, enter =(A1*B1). • Find the % of a total: Put the total in column A and number completed in B. In column C, enter =(B1/A1). • Decrease by %: Use the formula =A1*(1-B1). Original number is in A and the percentage to reduce by is in B. This article explains how to calculate a percentage in Excel using various methods, such as How to Calculate Percentage in Excel Although there's no basic percentage formula in Excel, you can multiply a number by a percentage using a formula. For example, if you have a column containing numbers and want to calculate 10% of one of those numbers, enter 10% in another cell, and then use a formula using the asterisk as the Multiply the Cells in a Column by the Same Percentage You can quickly calculate all the numbers in a column by the same percentage using the same formula with a few extra steps. For instance, if you want to calculate 7% tax for the numbers in column A and display it in column C, you would use the following method: How to Find the Percentage of a Total Another option is to calculate the percentage of a total. For instance, if you're trying to save $1,500 and are up to $736 in your savings account, you might want to know what percentage of your goal you've reached.
