what is the percentage change from 92 to 86.5
over a 1/2
Suppose you start with a number x and it increases to a number y.There are two ways to get to the answer. They are mathematically equivalent and which one you use is up to you.Method 1Step 1: Calculate the z = y - xStep 2: Convert to percentage: 100*z/xMethod 2:Step 1: Calculate increased percentage: 100*y/xStep 2: Calculate percentage increase: 100*y/x - 100
Two out of three is 66% and two out of four is 50%
10 as a percentage of 2 is 500% but 2 as a percentage of 10 is 20%
Turn them into a fraction and then multiply it by 100

over a 1/2
It is 40%
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

one 40th of total, but you can also work on 2%
between 2% and 15%
Two out of three is 66% and two out of four is 50%
The difference between the two is 2 units. Divide 2 by 52 and you get a be 3.8% increase.
2%A percentage of 2 is really too high. Between the age of 15-19, there's a 1.3 in 1,000,000 (one million) chance of getting breast cancer. If my calculations are correct, this is a percentage of 0.00013.
