Hello there!
First you had to solving by the fractions parts.
[tex]\frac{5}{9}+\frac{7}{9}=\frac{12}{9}[/tex]
Then you reducing by the fraction parts of 12/9.
[tex]\frac{12}{9}=\frac{4}{3}[/tex]
And finally, you simplify by the fraction parts of 4/3.
[tex]\frac{4}{3}=1 \frac{1}{3}[/tex]
Solution by Formulas
Applying the fractions formula for addiction.
[tex]\frac{(5*9)+(7*9)}{9*9}[/tex]
[tex]\frac{45+63}{81}[/tex]
[tex]=\frac{108}{81}[/tex]
Simplifying 108/81 and the answer is
[tex]=1 \frac{1}{3}[/tex]
Hope this helps!
