Question

What is the percent increase on 438,000 from 561,000

Answer 1

(561000-438000)/438000 x 100%
=123000/438000 x 100%
=28,08 %

Answer 2

So, first you have to put the amount of decrease/increase over the original amount. (like a fraction!) then you are trying to find the percent so you would do x over 100. so it would look like; 438,000       x
                                                   -----------  =  -----
                                                    561,000     100
Then you would cross multiply (438,000 times 100 and 561,000 times x [which would be x])  and it would look like;  43,800,000 = 561,000x

(a shortcut for 0's is that if theres the same amount of them on each side just cross them out! It gives you the same amount every time!)

43,800=561x      and finally you would divide 43,800 by 561 and your answer is 78.07%
Hope I helped! :)
