Ineed with starring the answer in mixed fraction

Greetings!

"Evaluate: -7/3-1 2/9."...

First, we must convert the mixed number into an improper fraction. This is done by multiply to whole number of the fraction (1 2/9) by the denominator. Then add this number to the numerator.

1*9=9
9+2=11
11/9

-7/3-11/9
Now we must find a common denominator for both fractions.
-21/9-11/9
=-32/9

The answer is -32/9.

Hope this helps.
