40 x 10 x 20 = 8000
To find 10% divide by 10. 10% = 9 So 20% = 9 x 2 = 18 Finally 20% off 90 = 90 - 18 = 72
If you mean 9/2 divided by 27/20 then the answer is 10/3 in its simplest form
9 x 20 = 180
if you are solving for x, then x=-10/3
9/10 of 20 = 18

0.2 x 300 x 10^9 = 2 x 30 x 10^9 = 6 x 10^10 = 60,000,000,000
0.2 recurring = 2/9, 0.45 = 9/20. Multiplying 2/9 x 9/20 gives 2/20 or 1/10 or 0.1.
40 x 10 x 20 = 8000
x-6-x-4=10-x -10=10-x -20=-x x=20 check: 20-6-20-4=10-20 -10=-10√
To find 10% divide by 10. 10% = 9 So 20% = 9 x 2 = 18 Finally 20% off 90 = 90 - 18 = 72
20/x = 9 Divide each side by 20. you get 1/x = 9/20. flip both sides. you get x = 20/9
The greatest common factor of 20 and 90 is 10.10 x 2 = 2010 x 9 = 90
