It is: 209 = 512,000,000,000 or as 5.12*1011 in scientific notation
3 to the 2nd power plus 5 x 4 - 9 = 20 32 + 5 x 4 - 9= 9 + 20 - 9= 20
9 percent of 20 = 1.89% of 20= 9% * 20= 0.09 * 20= 1.8
20 = 0.45
29
9 percent of 20 = 1.89% of 20= 9% * 20= 0.09 * 20= 1.8
9 out of 20 = 9/20 = 9 ÷ 20 = 0.45: 0.45 x 100 = 45%
9 9/20
perhaps you mean without using any other numbers? a lot depends on your constraints 9/9+9=10 which is 20 expressed in base 20 if you allow transformal mapping use Y=Nx20/27. Then each 9 transforms to 20/3 and Y1+Y2+Y3=20 There may be other transforms not involving constants that work. For instance, if we round our result to the nearest 10, ROUND [sqrt(9) x sqrt(9) + 9 ] gives 20. OR for some unspecified power N, we wish 9^n+9^n+9^n=20 using n~ 1.1582 solves the relation
It is 9/20
9/20 as a percentage = 100*9/20 = 45%
9 over 20:= 9/20 in fraction
11/20 divded by 9/20 = 11/9
