well 20 x 90 = 180, 20 x 9 = 18 add them together and you get 198
99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99
x/100 = 99/225 x = (99 x 100)/225 x = 9900/225 x = 44 The answer is 44%
99 x 99 = 9801
(99 x 3) = (100 - 1) x 3 = 300 -3 = 297
(300) x (99/100) = 3 x 99 = 297
Factor out each term to get: 20 = 2² x 5 99 = 3 x 33 = 3² x 11 Since these terms don't have the common factor, the common factor is 1.

1 x 99 = 99 2 x 99 = 198 3 x 99 = 297 4 x 99 = 396 5 x 99 = 495 6 x 99 = 594 7 x 99 = 693 8 x 99 = 792 9 x 99 = 891 10 x 99 = 990 11 x 99 = 1089 12 x 99 = 1188
1 x 99 = 99 99 x 1 = 99 3 x 33 = 99 33 x 3 = 99 9 x 11 = 99 11 x 9 = 99
99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99
20% off of $99 = $79.2 = 20% discount applied to $99 = $99 - (20% * $99) = $99 - (0.20 * $99) = $99- $19.8 = $79.2
Multiply 4.95 X .20 = .99 .99 + 4.95 = 5.94

99/20 cannot be simplified.
There are three:99 = 1 x 9999 = 3 x 3399 = 9 x 11
1 x 99 = 99 3 x 33 = 99 9 x 11 = 99
To express 0.60 with the decimal part repeating as a fraction, we can set x = 0.60 repeating. Multiplying x by 100 to shift the decimal two places gives 100x = 60.60 repeating. Subtracting the original x from 100x eliminates the repeating decimal, yielding 99x = 60. Dividing both sides by 99 gives x = 60/99, which simplifies to 20/33. Therefore, 0.60 repeating as a fraction is 20/33.
