1 and 5 are wrong. The other three are correct.
1. 1 7/8 + 1/9
= 15/8 + 1/9 , LCD = 72
= 135/72 + 8/72
= 143/72
none of the choices match
2.
8 8/9 - 5 1/11
= 80/9 + 56/11
= 880/99 + 448/99
= 1328/99
none of your choices match this.
3.3.) 7 2/3 x 3 7/9
= 23/3 x 34/9
= 782/27
not your choice.
are you just guessing?
