Answer 1

9998/9+998/9+98/9
=9999/9-1/9+999/9-1/9+99/9-1/9
=1111-1/9+111-1/9+11-1/9
=（1111+111+11）-（1/9+1/9+1/9）
=1233-3/9
=1233-1/3
=1232又2/3
拆分、凑整、化简，简便运算。

Answer 2

=1111+111+11-1/9-1/9-1/9
=1232又2/3

Answer 3

9998/9+998/9+98/9
=（9998+998+98）/9
=11194/9
=1243.777777777778

Answer 4

9998/9+998/9+98/9
=
(9998+1-1)/9+(998+1-1)/9+(98+1-1)/9
=
(9999-1)/9+(999-1)/9+(99-1)/9
=
1111+111+11-1/9-1/9-1/9
=1233-1/3
=1232+2/3

Answer 5

简便计算方法如下

1、提取原式：9998/9+998/9+98/9

2、计算过程：

   =(9998+998+98)/9

   =(10000+1000+100-6)/9

   =11100/9-6/9

   =1233又3/9-6/9

   =1232又6/9

   =1232又2/3

3、计算结果：1232又2/3
