Question

How do I do this? I don't get it

Answer 1

First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.

Answer 2

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.     

The Correct Answer Is ----> 50%
