Step-by-step explanation:

In number 1 I think they did a typo so we can just put   6   3/4.  So if you know what to do go for it :D

Hope this helps :D

1. 7 5/8     2.  1/6    3. 2 2/9

Step-by-step explanation:

For number one, convert 3/4 to eights because we cant subtract fourths from eighths. It is 6/8. 7/8 + 6/8 = 13/8 = 1 5/8 . 1 5/8 + 6 = 7 5/8.

For number 2: We 2/3 to sixths because we cant subtract sixths from thirds. 2/3 = 4/6. 5/6 - 4/6 = 1/6.

For number 3: Just subtract. 8 - 5 7/9 =  2 2/9.
