(200-2)÷9=

(3000-3)÷9=

(40000-4)÷9=

______÷______=______

______÷______=______

______÷______=______

______÷______=______.

答案

(10-1)÷9=1,

(200-2)÷9=22,

(3000-3)÷9=333,

(40000-4)÷9=4444,

由此可得:

(500000-5)÷9=55555,

(6000000-6)÷9=666666,

(70000000-7)÷9=7777777,

(800000000-8)÷9=88888888.

故答案为:(500000-5),9,55555;(6000000-6),9,666666;(70000000-7),9,7777777;(800000000-8),9,88888888.
