Answer 1

1*9 = 09,0+9 = 9,9 * 1 = 9,9 - 1 = 8； 8 /8 = 1
2*9 = 18,1+8 = 9,9 * 2 = 18,18 - 2 = 16；16/2 = 2
3*9 = 27,2+7 = 9,9 * 3 = 27,27 - 3 = 24；27/3 = 3
4*9 = 36,3+6 = 9,9 * 4 = 36,36 - 4 = 32；36/4 = 4
5*9 = 45,4+5 = 9,9 * 5 = 45,45 - 5 = 40；45/5 = 5
6*9 = 54,5+4 = 9,9 * 6 = 54,54 - 6 = 48；54/6 = 6
7*9 = 63,6+3 = 9,9 * 7 = 63,63 - 7 = 56；63/7 = 7
8*9 = 72,7+2 = 9,9 * 8 = 72,72 - 8 = 64；72/8 = 8
9*9 = 81,8+1 = 9,9 * 9 = 81,81 - 9 = 72；81/9 = 9
