9 x 1 = 9 | 9 x 2 = 18 | 9 x 3 = 27 | 9 x 4 = 36 |
1 x 9 = 9 | 2 x 9 = 18 | 3 x 9 = 27 | 4 x 9 = 36 |
9 x 5 = 45 | 9 x 6 = 54 | 9 x 7 = 63 | 9 x 8 = 72 |
5 x 9 = 45 | 6 x 9 = 54 | 7 x 9 = 63 | 8 x 9 =72 |
(1+1+1+1+1+1+...) x X = (9+9++9+9+9+9+9+9+9) + 9
100 số 1
(1 x 100) x X = (9 x9) +9
100 x X = 81 +9
100 x X = 90
X = 90 : 100
X = 0,9
