Percentages are found by dividing the given amount from the whole and multiplying the decimal result by 100. In most cases, you need a calculator to ensure the proper amount, especially with regards to decimal spaces.
Know MoreDetermine the given amount that defines the percentage that you are looking to calculate. For example, if you were given a problem statement that said seven eggs were taken out of a dozen, the given amount would be the seven eggs.
Divide the given amount by the total to produce a decimal result. From the previous example, you would perform the following calculation: 7/12 = 0.5833. You can determine how many decimal spots you need in your calculation.
Multiply the decimal result by 100 to get the percentage amount. This can also be done by moving the decimal two spaces to the right. Performing either of these actions with the previous calculation produces an answer of 58.33 percent.
If you are given the percentage and one of the amounts, you may find the other amount by rearranging the formula. Using the previous example, if you were given the decimal and the total, you would set up the equation as follows: x/12 = 0.5833. You would rearrange the equation and solve as shown: x = 12(0.5833) = 7.
Calculating percentage from a decimal or a fraction requires multiplying by 100. For a decimal, this means moving the decimal point two places to the right; for example, .28 equals 28 percent. To convert fractions, the numerator is divided by the denominator and the quotient is multiplied by 100.
Full Answer >A decimal number can be transformed into a percentage by multiplying it by 100. If the number is a fraction, it is first necessary to convert it into a decimal by dividing the numerator by the denominator.
Full Answer >Converting the percentages to decimals then finding the average of these figures and reconverting back to a percentage is the easiest way to do this. You need the percentages you wish to average, paper, a pencil and a calculator.
