How do i find a percent of a quantity?
Multiply the quantity by the percentage and divide by 100. So, to find 45% of 180, calculate (180*45)/100
How do you find the percent?
Usually you compare two quantities, to find out how much percent one is of another. The second quantity is often a total, but it need not be so. Divide the first quantity by the second, and multiply the result by 100, to get the percentage.
How do you find percentage change in quantity demanded when only given original quantity?
you cannot. you need more info.
Why do you need to calculate percentage change in an experiment?
To find the difference between the two numbers in percent form
What is the percent change from 350 to 420 yards?
To find the answer to this, first divide 420 by 350, which is 1.2. Get the percent value of this by multiplying 1.2 by 100, so the percent value must be 120%. Since we are looking for percent change, subtract 100 from that to get 20%. The answer is "350 changes 20% to become 420", or "420 is 20% more than 350".
