100 x 90 = 9,000
Expanded Notation of 90 = (9 x 101) + (0 x 100)
100 x 0.9 = 90
First one 90 x 0.6 = 54 100 x 0.5 = 50
0.3 % of 90 = 0.3/100 x 90 = 0.27
x/y*100=% For example: 45/90*100=% 1/2*100=% .5*100=% 50=% Check: 50% of 90 = x 50/100 * 90 = x .5 * 90 = x 45 = x
90 = 100% X = 2.5% X = 2.5x90 ÷ 100 X = 2.25
190 100 x 0.90 = 90 100 + 90 = 190
consider the num to be "X" so (90/100)*x = 207 by transposing we get x=(207*100)/90 x=230
100 x 90 = 9,000
% rate:= (90/136) x 100%= 0.6618 x 100%= 66.18%
Expanded Notation of 90 = (9 x 101) + (0 x 100)
90 = 100% 25 = X% X = 25x100 ÷ 90 X = 27.777777777777%
(New - Original)/Original x 100% = Differences/Original x 100% = +% (increased) = -% (decreasing) ---- e.g. 1) (100 - 90)/90 x 100% = 10/90 x 100% = 1000/90% = +11 1/9% ---- e.g. 2) (60 - 80)/80 x 100% = -20/80 x 100% = -2000/80% = -25%
