For this case we have:

[tex]3 \frac {8} {9} = \frac {27 + 8} {9} = \frac {35} {9} = 3.8888[/tex]

Round the nearest whole, that is, to 4.

[tex]2 \frac {5} {6} = \frac {12 + 5} {6} = \frac {17} {6} = 2.8333[/tex]

Round the nearest whole, that is, to 3.

So, rewriting we have:

[tex]4 + 3 = 7[/tex]

ANswer:

[tex]3 \frac {8} {9} +2 \frac {5} {6} = 7[/tex]
