First: work out the difference (increase<span>) between the two numbers you are comparing. Then: divide the </span>increase<span> by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage<span> decrease.</span>
Think of this as a fraction. Lets think the fraction is based off of the number "4" 4,8,12,16 Makes the fraction 1\4 (because there's 4 numbers total) then lets add the extra 2 numbers of 4+4.....4,8,12,16,20 ,24 . that makes 1\6. so now all you do is convert the fraction into a percentage.
