99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99
99 x 99 = 9801
x/100 = 99/225 x = (99 x 100)/225 x = 9900/225 x = 44 The answer is 44%
(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
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.
