Best Answer

say the number you start out with is A, and the number it becomes is B.

to find the percentage, you must subtract A-B. Then divide the answer by A and multiply by 100% to get the percentage.

(A-B)/A * 100%

ex.

10 is the number you start with, 4 is the second number.

So A=10 and B=4

10-4=6

6/10=0.6

multiply by 100% to get the percentage 60%

so the percent of decrease is 60%

How do you find the percentage of change between 3 numbers?

A percentage change can only be found between TWO numbers. If you are given more than two, the question may be asking for either- the increase from the first number to the rest of the numbers- the increase between successive pairs of number (for example a to b, b to c)To find the difference between one number and the next, subtract the first number from the second, then divide by the first number and multiply by 100. This gives the percentage of increase. If the result is negative, the second number being lower, this is the percentage of decrease.*The percentage change does not work in reverse - the percentage is always expressed in terms of the original (first) value.Example:2 and 4 - the increase is 2, divided by 2, times 100, which is a 100% increase.4-2 = 2, 2/2 = 1, 1 x 100 = 1004 and 2 - the decrease is -2, divided by 4, times 100, which is a 50% decrease.2-4 = (-2), (-2)/4 = 0.50, 0.50 x 100 = 50
