1 x 625, 5 x 125, 25 x 25, 125 x 5, 625 x 1 = 625
625
625 = (6 x 100) + (2 x 10) + (5 x 1)
Call the answer x. x times 9% = 113. 9% is 9/100 so x times 9/100 is 113. Therefore x times 1/100 would be one ninth of 113, which is 125/9, or 12.55555... If this is 1/100 of x, x is that times 100, which is 1255.5555555...
log x + 2 = log 9 log x - log 9 = -2 log (x/9) = -2 x/9 = 10^(-2) x/9 = 1/10^2 x/9 = 1/100 x= 9/100 x=.09
(6 x 100) + (2 x 10) + (5 x 1) = 625
1 x 625, 5 x 125, 25 x 25, 125 x 5, 625 x 1 = 625
625
Approximately 0.176% Solve the following equation 5120/100=9/x x=9*100/5120=900/5120, or about .176%

625 = (6 x 100) + (2 x 10) + (5 x 1)
Call the answer x. x times 9% = 113. 9% is 9/100 so x times 9/100 is 113. Therefore x times 1/100 would be one ninth of 113, which is 125/9, or 12.55555... If this is 1/100 of x, x is that times 100, which is 1255.5555555...
625 = (6 x 100) + (2 x 10) + (5 x 1)
If x=9, x=9
log x + 2 = log 9 log x - log 9 = -2 log (x/9) = -2 x/9 = 10^(-2) x/9 = 1/10^2 x/9 = 1/100 x= 9/100 x=.09
9/10 divided by 10/9 equals 9/10 x 9/10 equals 81 /100
Expressed as a percentage, 500/625 x 100 = 80 percent.
