JulijaS [17]

The answer is 25%.

First: work out the difference between the two numbers you are comparing.  

Decrease = Original Number - New Number

35-28=7


Then: divide the decrease by the original number and multiply the answer by 100.  % Decrease = Decrease ÷ Original Number × 100


7÷

28=.25

.25*100=25

<h2>Answer is 25%.</h2>
