If your calculator has a percentage button, press it to determine the percentage. If your calculator does not have such a button, multiply your previous answer by to determine the percentage:. If the omitted term is the part, use the calculator to multiply the whole by the percentage to determine the answer. If your calculator has a percentage button, the calculation is as follows:. If your calculator does not have a percentage button, you must first divide the percentage by If the omitted term is the whole, divide the part by the percentage to determine the answer.
If your calculator does not have a percentage button, you must divide the percentage by before completing the calculation:. Double-check your answer, particularly if it seems unlikely. You may have made a calculation error at some point. Nicole Askin has been writing since Her work has appeared in "Juice," "Ibid," and a number of websites. She is currently pursuing a degree in honors English, music and creative writing at the University of Western Ontario.
You can then multiply this answer by the whole to determine the part:. Percentage increase and decrease are calculated by computing the difference between two values and comparing that difference to the initial value. Mathematically, this involves using the absolute value of the difference between two values, and dividing the result by the initial value, essentially calculating how much the initial value has changed. The percentage increase calculator above computes an increase or decrease of a specific percentage of the input number.
It basically involves converting a percent into its decimal equivalent, and either subtracting decrease or adding increase the decimal equivalent from and to 1, respectively. Multiplying the original number by this value will result in either an increase or decrease of the number by the given percent.
