n = 3030 percent of n equals 930% * n = 930%/100% * n = 90.3n/0.3 = 9/0.3n = 30

90 is the 100%.100% :N = 30% : 2730%N = 27 (100%)N = 27(100%)/30%N = 2700/30N = 90

0.9 n = 142.2n = 142.2 / 0.9 = 158
90
Is over of equals % over 10012/N=8/10012x100=Nx81200=8Ndivide both sides by 8.150=N12 is 8 percent of 150.

n = 3030 percent of n equals 930% * n = 930%/100% * n = 90.3n/0.3 = 9/0.3n = 30

N*(1+90%) = 156 that is N*1.9 = 156 so N = 156/1.9 = 82.1053 approx.Another Answer:-It could be 15.6 because 156 minus 90% = 15.6And so: (156-15.6)/156 times 100 = 90% increase
n is 6
90 is the 100%.100% :N = 30% : 2730%N = 27 (100%)N = 27(100%)/30%N = 2700/30N = 90
If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9
90% = 90/100 = 0.9 90% of n = 36 0.9 x n = 36 n = 36 / 0.9 = 40 36 is 90% of 40.
