How do you find the whole number from the percentage increase?<br><br><br>(Give an example)
hjlf
Say the percentage increase is 25%. If you have the whole number of 30 then you would multiply 30 by .25. You should therefore get 7.5 once both are multiplied. That means you should add 7.5 to 30, and your final answer will be 37.5.
