25% of x=28 0.25x=28 x/4=28 x=28x4 x=112 ;)
25 x 28 = 700
% rate= (28/25) x 100%= 1.12
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109

25 x 28 = 700
3 and 28 3 - 28 = -25 (or 28 - 3 = 25) 3 x 28 = 84
% rate= (28/25) x 100%= 1.12
5 x 5 = 25 2 x 2 x 7 = 28 3 x 3 x 5 = 45
28 x 25 = 700 (700 square feet)
% increase:= (|32-25| /25) x 100%= (7/25) x 100%= 0.28 x 100%= 28%
If their difference is 25 then the larger number is the smaller number plus 25. Let the smaller number be x then the larger number is x + 25 → their sum is x + (x + 25) = 81 → 2x = 56 → x = 28 → the two numbers are 28 and 53.
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109

7/28 x 100% = 25%
x% = x/100 = x:100 if x happens to have a common factor with 100, then simplify it. it is as easy as that. for example, 28% = 28/100 = 7:25 25% = 25/100 = 1:4
