I guess you mean find the percentage of one number of another, eg what percentage of 100 is 30:
Divide the number for which the percentage of the other is required by the other number (making it a fraction of the second number) and multiply it by 100 %.
/ The 2 numbers * By 100 and there is your answear!
what is the percentage change from 92 to 86.5
You cannot. Percentage is a binary operator: you input two numbers and get one number as a percentage of the other or, equivalently, the percentage change from one to the other.
The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.
To find the base, percentage and rateperce ntage = base * rate (rate in decimal)base = percentage/rate (rate in decimal)rate = percentage/base * 100%Example:Base = 10Percentage = 2Rate?Rate = 2/10 * 100% = 20%

its easy
Find 2 numbers
The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.

2.25% = 0.0225
In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.
To find the percentage of one number you divide the numbers then multiply the answer by 100. For an example, if you want to find the percentage of four that the number three is you divide three by four and then multiply the result ,which is 0.75, by 100 and your result or percentage would be 75%!
If there are 2 numbers as the median, you find the mean of those 2 numbers. (add both numbers and divide by 2)
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
